Genes affected

SPATA48 (HGNC:):

SPMIP7 (HGNC:22564): (sperm microtubule inner protein 7)

ZPBP (HGNC:15662): (zona pellucida binding protein) ZPBP is one of several proteins that are thought to participate in secondary binding between acrosome-reacted sperm and the egg-specific extracellular matrix, the zona pellucida (McLeskey et al., 1998 [PubMed 9378618]).[supplied by OMIM, Aug 2008]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.96).
• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.901 is higher than 0.05.
