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

Verdict is Likely_benign. Variant got -4 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.06691632).
• BP6: Variant 11-65850514-G-A is Benign according to our data. Variant chr11-65850514-G-A is described in ClinVar as [Likely_benign]. Clinvar id is 2521754.Status of the report is criteria_provided_single_submitter, 1 stars.

Ambry Genetics

May 10, 2023

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
