Genes affected

SPATA2 (HGNC:14681): (spermatogenesis associated 2) Enables signaling receptor complex adaptor activity and ubiquitin-specific protease binding activity. Involved in several processes, including protein deubiquitination; regulation of necroptotic process; and regulation of tumor necrosis factor-mediated signaling pathway. Located in cytoplasm; fibrillar center; and nucleoplasm. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.74).
• BA1: GnomAd4 highest subpopulation (SAS) allele frequency at 95% confidence interval = 0.541 is higher than 0.05.
