| Mendeliome v1.4188 | SUN5 |
Zornitza Stark gene: SUN5 was added gene: SUN5 was added to Mendeliome. Sources: Literature Mode of inheritance for gene: SUN5 was set to BIALLELIC, autosomal or pseudoautosomal Publications for gene: SUN5 were set to 34159570; 33671757; 27640305 Phenotypes for gene: SUN5 were set to Spermatogenic failure, MONDO:0004983, SUN5-related Review for gene: SUN5 was set to GREEN Added comment: SUN5 encodes a testis‑specific SUN‑domain protein that anchors the sperm head to the tail. Multiple independent studies have identified biallelic loss‑of‑function SUN5 variants in >30 individuals with acephalic spermatozoa syndrome. Functional studies—including Western blot, immunofluorescence, Sun5 knockout mouse models, HeLa splicing assays, Y2H/GST pull‑down and proteasome‑inhibition rescue—demonstrate loss of SUN5 protein and disrupted head‑tail coupling, supporting loss‑of‑function as the disease mechanism.

| Mendeliome v1.3322 | CCDC188 |
Chirag Patel gene: CCDC188 was added gene: CCDC188 was added to Mendeliome. Sources: Literature Mode of inheritance for gene: CCDC188 was set to BIALLELIC, autosomal or pseudoautosomal Publications for gene: CCDC188 were set to 41004021 Phenotypes for gene: CCDC188 were set to Male infertility due to acephalic spermatozoa, MONDO:0035153 Review for gene: CCDC188 was set to GREEN Added comment: 2 patients from 2 unrelated families with acephalic spermatozoa syndrome. WES identified biallelic variants in CCDC188 gene (1 x homozygous, 1 x compound heterozygous). The variants (c.481C > T [p.Gln161*] and c.1022 + 1G > A [p. K325Afs*110]) were rare in gnomAD and segregated in the family with heterozygous carrier parents. Western blotting, RT-PCR, qPCR, and immunofluorescence showed depletion of CCDC188 protein (and SUN5 and PMFBP1 protein) in patient sperm. Mutations in SUN5 and PMFBP1 genes account for 75% patients with acephalic spermatozoa syndrome. Sources: Literature |
