Comprehensive Disease Characteristics Report: Congenital Renal Artery Stenosis (CRAS)

Executive summary

Congenital/pediatric renal artery stenosis (RAS) is a narrowing of the renal artery(ies) present from birth or developing in childhood, often manifesting as renovascular hypertension (RVH). The central pathophysiologic concept is reduced renal perfusion, which activates the renin–angiotensin–aldosterone system (RAAS) and drives severe or refractory hypertension, with risk of end-organ injury (kidney atrophy/CKD, cardiac remodeling/heart failure, cerebrovascular complications). In modern pediatric practice, digital subtraction angiography (catheter angiography) remains the diagnostic gold standard, while percutaneous transluminal renal angioplasty (PTRA) is a common first-line revascularization strategy in appropriately selected children; outcomes vary by etiology, and restenosis/reintervention is frequent in complex arteriopathies and mid-aortic syndrome (MAS). (goyal2023pediatricrenovascularhypertension pages 1-2, persu2021beyondatherosclerosisand pages 4-5, pytlos2024renalarterystenosis pages 12-14, redhead2024cardiovascularoutcomesimprove pages 1-2)

  • Limitation of current tool-retrieved corpus: authoritative ontology identifiers (MONDO ID, MeSH descriptor/ID, ICD-10/ICD-11 codes, Orphanet, OMIM) specific to “congenital renal artery stenosis” were not directly retrievable from the available full-text evidence captured in this run. This report therefore provides evidence-based clinical definitions and syndromic genetic identifiers at the gene/syndrome level (e.g., NF1, ELN/Williams-Beuren, JAG1/Alagille), but cannot reliably populate a MONDO/MeSH/ICD mapping without additional database-specific retrieval. (pytlos2024renalarterystenosis pages 1-2, warejko2018wholeexomesequencing pages 3-5, coleman2022moleculargeneticevaluation pages 1-2)

1.3 Synonyms and alternative names (commonly used)

Common overlapping terms used in the literature include: * Renovascular hypertension (RVH) in children (clinical syndrome of hypertension due to renovascular lesions) (goyal2023pediatricrenovascularhypertension pages 1-2) * Renal artery stenosis (RAS) (pytlos2024renalarterystenosis pages 1-2) * Mid-aortic syndrome (MAS) / abdominal aortic coarctation (pytlos2024renalarterystenosis pages 1-2)

1.4 Evidence source type (patient-level vs aggregated)

Most evidence for pediatric/congenital RAS is derived from: * Observational cohorts/series (e.g., 152-child longitudinal cohort with echo follow-up after interventions) (redhead2024cardiovascularoutcomesimprove pages 1-2) * Retrospective pediatric series (e.g., 25 cases over 13 years in a defined pediatric catchment) (peco‐antic2016associatedextrarenalvascular pages 4-5) * Systematic/structured reviews synthesizing pediatric RAS/MAS data (pytlos2024renalarterystenosis pages 1-2, pytlos2024renalarterystenosis pages 12-14) * Genomic cohort studies (e.g., WES in MAS families; NF1-focused molecular profiling of stenotic arteries) (warejko2018wholeexomesequencing pages 1-2, coleman2022moleculargeneticevaluation pages 1-2)

2. Etiology

2.1 Disease causal factors (current understanding)

Pediatric/congenital RAS is etiologically heterogeneous and can be classified into: * Non-inflammatory arteriopathies: particularly fibromuscular dysplasia (FMD), described as a major contributor to pediatric RAS in North America/Europe. (pytlos2024renalarterystenosis pages 2-4) * Inflammatory large-vessel vasculitis: notably Takayasu arteritis, which is regionally prevalent in some pediatric series. (goyal2023pediatricrenovascularhypertension pages 1-2, pytlos2024renalarterystenosis pages 2-4) * Syndromic/genetic causes: especially neurofibromatosis type 1 (NF1), Williams–Beuren syndrome (WBS; ELN region deletion), and Alagille syndrome (JAG1/NOTCH pathway). (persu2021beyondatherosclerosisand pages 4-5, warejko2018wholeexomesequencing pages 3-5) * Anatomic distribution phenotypes: focal stenosis vs multifocal disease; MAS is a congenital or acquired narrowing of the abdominal aorta often involving renal arteries. (goyal2023pediatricrenovascularhypertension pages 1-2, pytlos2024renalarterystenosis pages 1-2)

2.2 Risk factors

Genetic/syndromic risk factors (monogenic contributors): * MAS has a high monogenic yield by whole-exome sequencing (WES): likely causal dominant mutations were found in 15/35 families (≈42.9%), involving NF1, JAG1, ELN, GATA6, RNF213. (warejko2018wholeexomesequencing pages 1-2) * In the same MAS cohort, the most frequent gene was NF1 (6/35 families; 17.1%), followed by JAG1 (4/35; 11.4%) and ELN (3/35; 8.6%). (warejko2018wholeexomesequencing pages 3-5)

Clinical epidemiologic risk context: * In one pediatric RVH/RAS cohort, NF1 accounted for 12% of cases. (peco‐antic2016associatedextrarenalvascular pages 4-5)

Population/region-dependent etiologic spectrum: * A 2023 pediatric interventional radiology review notes that FMD is commonly reported in developed countries, whereas Takayasu arteritis is more common in parts of Asia/Africa. (goyal2023pediatricrenovascularhypertension pages 1-2)

2.3 Protective factors

No specific protective genetic variants or environmental protective factors for congenital/pediatric RAS were identified in the retrieved evidence set.

2.4 Gene–environment interactions

No gene–environment interaction studies specific to congenital/pediatric RAS were identified in the retrieved evidence set.

3. Phenotypes

3.1 Core clinical phenotype spectrum

Pediatric RAS/RVH may be clinically silent and detected only by blood pressure measurement; a pediatric cohort reported ~1/3 asymptomatic despite severe hypertension, highlighting the importance of screening/measurement rather than symptom-driven diagnosis. (peco‐antic2016associatedextrarenalvascular pages 4-5, goyal2023pediatricrenovascularhypertension pages 1-2)

Table: This table maps major pediatric/congenital renal artery stenosis and renovascular hypertension findings to suggested HPO terms, with onset and frequency notes where reported. It is useful for knowledge-base curation of phenotype annotations and evidence-backed clinical features.

3.2 Frequency/severity/progression (selected quantitative data)

3.3 Quality of life impact

Direct patient-reported outcome measures (e.g., PedsQL, PROMIS) were not identified in the retrieved sources. Indirectly, severe hypertension and need for repeated procedures/medications imply substantial burden. (pytlos2024renalarterystenosis pages 12-14, redhead2024cardiovascularoutcomesimprove pages 1-2)

4. Genetic / molecular information

4.1 Causal genes and syndromes (strongly supported)

NF1 (neurofibromatosis type 1) * In a prospective cohort of 102 pediatric RVH patients with RAS ± abdominal aortic coarctation, 13 (12.5%) had clinical NF1. (coleman2022moleculargeneticevaluation pages 1-2)

JAG1 (Alagille syndrome) * JAG1 truncating variants were identified in multiple families with syndromic MAS in WES-based studies. (warejko2018wholeexomesequencing pages 5-6, warejko2018wholeexomesequencing pages 1-2)

ELN region (Williams–Beuren syndrome; 7q11.23 deletion) * WES/CNV analysis in MAS families identified ELN/Williams-related deletions in a subset (3/35 families). (warejko2018wholeexomesequencing pages 3-5, warejko2018wholeexomesequencing pages 1-2)

Additional monogenic genes reported in MAS WES cohorts * GATA6 and RNF213 were each identified in single MAS families in the WES study. (warejko2018wholeexomesequencing pages 1-2)

4.2 Pathogenic variants (examples, where available in evidence)

The MAS WES study reported a range of NF1 variant types (missense, splice-site, frameshift, truncating) and provided specific examples (e.g., c.1166A>G p.H389R; c.1260+5G>A; c.3457_3460del p.L1153Mfs*4). (warejko2018wholeexomesequencing pages 3-5)

4.3 Molecular mechanisms (authoritative mechanistic evidence)

NF1 vasculopathy (human lesion ‘omics’ + histology): * Human stenotic renal arteries in NF1 show a consistent remodeling pattern (intimal thickening, disrupted internal elastic lamina, medial thinning) and transcriptomic evidence of NF1 haploinsufficiency and inflammatory/proliferative signaling: approximately 5-fold reduction in NF1 expression, MAPK pathway activation, and increased MCP1. (coleman2022moleculargeneticevaluation pages 1-2) * Immunostaining demonstrated markedly increased pERK1 (Ras–MAPK pathway activity) in NF1 stenotic artery tissue. (coleman2022moleculargeneticevaluation pages 8-9)

Causal chain (NF1 example): germline NF1 variant → neurofibromin haploinsufficiency → Ras–MAPK activation + MCP1/CCR2-mediated monocyte recruitment and vascular smooth muscle proliferative responses → neointimal hyperplasia and arterial remodeling → renal hypoperfusion → RAAS activation → severe hypertension and downstream end-organ injury. (coleman2022moleculargeneticevaluation pages 8-9, redhead2024cardiovascularoutcomesimprove pages 1-2)

4.4 Epigenetics, modifier genes, and molecular profiling beyond NF1

No disease-specific epigenetic studies or multi-omics signatures (beyond NF1 arterial RNA-Seq in the retrieved corpus) were identified.

5. Environmental information

Congenital RAS is primarily developmental/genetic/structural in the retrieved sources. Environmental contributors (toxins, lifestyle) and infectious agents were not identified as primary causes in the retrieved evidence set.

6. Mechanism / pathophysiology

6.1 RAAS-driven renovascular hypertension

A central mechanistic statement supported in the pediatric literature is that renal artery stenosis reduces renal perfusion, activates the RAAS axis, and can drive severe hypertension and cardiac remodeling. (redhead2024cardiovascularoutcomesimprove pages 1-2, goyal2023pediatricrenovascularhypertension pages 1-2)

6.2 Suggested ontology mappings

GO Biological Process (suggested): * renin secretion / renin-angiotensin system regulation * regulation of systemic arterial blood pressure * vascular smooth muscle cell proliferation * inflammatory cell chemotaxis (monocyte chemotaxis)

Cell Ontology (CL) (suggested): * vascular smooth muscle cell * endothelial cell * monocyte / macrophage (CCR2+ inflammatory monocyte subset conceptually relevant)

These are suggested based on the described mechanisms (RAAS activation; VSMC proliferation; MCP1/CCR2 monocyte infiltration) rather than explicitly enumerated ontology IDs in the retrieved papers. (coleman2022moleculargeneticevaluation pages 8-9, redhead2024cardiovascularoutcomesimprove pages 1-2)

7. Anatomical structures affected

Organ/system level: * Kidney (renal parenchyma ischemia, atrophy) and renal arteries (primary lesion). (pytlos2024renalarterystenosis pages 1-2, persu2021beyondatherosclerosisand pages 11-12) * Cardiovascular system (hypertension-related cardiac remodeling; sometimes heart failure). (redhead2024cardiovascularoutcomesimprove pages 1-2) * Aorta and branch vessels in MAS (abdominal aorta, renal and visceral branch ostia). (pytlos2024renalarterystenosis pages 1-2)

UBERON suggestions (non-exhaustive): kidney; renal artery; abdominal aorta; heart left ventricle.

Lateralization: * Both unilateral and bilateral disease occurs; bilateral stenosis can be common. (goyal2023pediatricrenovascularhypertension pages 1-2)

8. Temporal development

9. Inheritance and population

9.1 Epidemiology (quantitative data available)

  • Childhood arterial hypertension prevalence: ~4%. (pytlos2024renalarterystenosis pages 1-2)
  • Renovascular disease contribution: 5–10% of secondary pediatric hypertension. (pytlos2024renalarterystenosis pages 1-2, peco‐antic2016associatedextrarenalvascular pages 4-5)
  • Incidence estimate (regional cohort): 25 pediatric RVH/RAS cases over 13 years in hospitals serving ~1 million children → ~1.9 per million children/year. (peco‐antic2016associatedextrarenalvascular pages 4-5)
  • MAS rarity: ~0.5–2% of aortic stenosis cases; among pediatric RVH cohorts, 20–48% may have combined renal artery plus mid-aortic narrowing. (pytlos2024renalarterystenosis pages 1-2)

9.2 Inheritance patterns (genetic etiologies)

10. Diagnostics

10.1 Imaging and diagnostic strategy

10.2 Differential diagnosis (etiologic breadth)

Differential includes non-inflammatory arteriopathies (FMD), vasculitis (Takayasu), syndromic vascular disease (NF1, WBS, Alagille), thromboembolism/catheter-related injury, extrinsic compression, trauma/radiation, and MAS. (pytlos2024renalarterystenosis pages 2-4, pytlos2024renalarterystenosis pages 1-2)

10.3 Genetic testing

For syndromic/diffuse disease and MAS phenotypes, reviews recommend evaluation for extrarenal involvement and referral for genetic evaluation/testing. (pytlos2024renalarterystenosis pages 2-4)

11. Outcome / prognosis

11.1 Blood pressure and cardiovascular outcomes after intervention

A 2024 longitudinal pediatric cohort (152 children with RVH undergoing ≥1 endovascular intervention, some with surgery) reported: * BP control achieved in 54.4% post-intervention * 45.9% reduced antihypertensive medications * 21.3% discontinued all antihypertensive therapy * Improvement in multiple echocardiographic parameters consistent with reversal/improvement of cardiac remodeling. (redhead2024cardiovascularoutcomesimprove pages 1-2)

11.2 Restenosis and reintervention

12. Treatment

12.1 Medical therapy

Children often require multi-drug antihypertensive therapy; however, medical therapy alone may be insufficient for durable BP control in anatomic lesions. (pytlos2024renalarterystenosis pages 1-2, pytlos2024renalarterystenosis pages 12-14)

Critical safety constraint (RAAS blockade): * ACE inhibitors/ARBs are absolutely contraindicated in bilateral RAS or RAS in a solitary kidney due to risk of acute renal failure/volume overload/pulmonary edema. (pytlos2024renalarterystenosis pages 12-14)

12.2 Endovascular and surgical interventions (real-world implementation)

Effectiveness (quantitative): * In a 2024 pediatric review synthesis, PTRA showed an overall cure rate of 36% and BP improvement in an additional 32%, with etiology-specific differences (e.g., higher success in Takayasu arteritis and NF1 than FMD in the summarized series). (pytlos2024renalarterystenosis pages 12-14)

12.3 MAXO (Medical Action Ontology) suggestions

  • Percutaneous transluminal angioplasty
  • Vascular stent placement
  • Surgical vascular reconstruction / bypass
  • Antihypertensive drug therapy
  • Aspirin antiplatelet therapy / peri-procedural anticoagulation

These MAXO actions are suggested based on interventions described in pediatric reviews and cohorts. (goyal2023pediatricrenovascularhypertension pages 1-2, pytlos2024renalarterystenosis pages 12-14, redhead2024cardiovascularoutcomesimprove pages 1-2)

12.4 Trials

No pediatric congenital RAS-specific interventional clinical trials with extractable NCT identifiers were identified via the clinical trials search in this run.

13. Prevention

Primary prevention is generally not applicable for congenital developmental lesions. Secondary/tertiary prevention in practice consists of: * routine pediatric BP measurement to avoid delayed diagnosis (given frequent asymptomatic presentation) (peco‐antic2016associatedextrarenalvascular pages 4-5) * early imaging workup when RVH is suspected (goyal2023pediatricrenovascularhypertension pages 1-2) * long-term surveillance for recurrence/restenosis in progressive syndromic vasculopathies (e.g., NF1) (persu2021beyondatherosclerosisand pages 4-5)

14. Other species / natural disease

No naturally occurring veterinary analogs or cross-species epidemiology were identified in the retrieved evidence set.

15. Model organisms

Mechanistic support for NF1 arteriopathy includes mouse model evidence implicating monocyte/macrophage lineage Nf1 haploinsufficiency, CCR2/MCP1-mediated inflammatory recruitment, and neointimal hyperplasia (as summarized within the NF1 molecular study). (coleman2022moleculargeneticevaluation pages 8-9)
