Genes affected

SPATA13 (HGNC:23222): (spermatogenesis associated 13) Enables guanyl-nucleotide exchange factor activity and identical protein binding activity. Involved in cell migration; plasma membrane bounded cell projection assembly; and regulation of cell migration. Located in several cellular components, including filopodium; lamellipodium; and ruffle membrane. [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=-0.9).
• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.611 is higher than 0.05.
