Genes affected

SIPA1L2 (HGNC:23800): (signal induced proliferation associated 1 like 2) This gene encodes a member of the signal-induced proliferation-associated 1 like family. Members of this family contain a GTPase activating domain, a PDZ domain and a C-terminal coiled-coil domain with a leucine zipper. A similar protein in rat acts as a GTPases for the small GTPase Rap.

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.72).
• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.464 is higher than 0.05.
