Genes affected

SNX32 (HGNC:26423): (sorting nexin 32) Predicted to enable phosphatidylinositol binding activity. Predicted to be involved in retrograde transport, endosome to Golgi. Predicted to be located in cytosol. Predicted to be active in endosome. [provided by Alliance of Genome Resources, Apr 2022]

CFL1 (HGNC:1874): (cofilin 1) The protein encoded by this gene can polymerize and depolymerize F-actin and G-actin in a pH-dependent manner. Increased phosphorylation of this protein by LIM kinase aids in Rho-induced reorganization of the actin cytoskeleton. Cofilin is a widely distributed intracellular actin-modulating protein that binds and depolymerizes filamentous F-actin and inhibits the polymerization of monomeric G-actin in a pH-dependent manner. It is involved in the translocation of actin-cofilin complex from cytoplasm to nucleus.[supplied by OMIM, Apr 2004]

ACMG classification

Our verdict: Uncertain_significance. The variant received 2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
