| SYCE1 report: key takeaways (provisional) | Summary |
|---|---|
| Overall judgment | **Partially supported (provisional).** Evidence retrieval was blocked in this session (no retrievable papers / no citable contexts), so this assessment is seed-only and requires manual verification against the cited PubMed records before curation use. |
| Most critical supporting evidence pointers (seed PMIDs) | **PMID:25062452** — familial human POI/primary amenorrhea with homozygous nonsense SYCE1 variant; https://pubmed.ncbi.nlm.nih.gov/25062452/ . **PMID:32402064** — model evidence for absent/reduced SYCE1 and synapsis-related infertility mechanism; https://pubmed.ncbi.nlm.nih.gov/32402064/ . **PMID:34718620** — SYCE1 variants reported to disrupt interaction with SYCP1 and/or C14ORF39/SIX6OS1, affecting SC assembly; https://pubmed.ncbi.nlm.nih.gov/34718620/ . **PMID:35718780** — human NOA cases with SYCE1 CNVs and pachytene-stage arrest on H&E/IF; https://pubmed.ncbi.nlm.nih.gov/35718780/ . |
| Most critical missing evidence | Full-text confirmation of exact variant nomenclature and zygosity/phasing; segregation and family/case counts; endocrine data (e.g., FSH/AMH, testosterone, inhibin B); ovarian imaging and follicle depletion; detailed biopsy/immunostaining markers; direct human evidence for checkpoint activation/apoptosis; and any 2023–2024 follow-up studies. |
| Top curator actions | Manually review the four seed PMIDs; verify whether all pathogenic human cases are truly biallelic; extract 46,XX and 46,XY phenotype details; confirm evidence for SYCE1 interaction defects with SYCP1 and C14ORF39/SIX6OS1; distinguish direct human evidence from mouse/in vitro inference; and update the entry only after full-text verification. |


*Table: This table gives a compact provisional summary of the SYCE1-related gametogenic failure mechanism assessment based on the seed PMIDs only. It highlights the current judgment, the main evidence pointers, the most important missing information, and the highest-priority curator verification steps.*
