Genes affected
SGSM1 (HGNC:29410): (small G protein signaling modulator 1) Enables GTPase activator activity and small GTPase binding activity. Predicted to be involved in activation of GTPase activity and intracellular protein transport. Predicted to act upstream of or within positive regulation of transcription by RNA polymerase II. Located in cytoplasmic vesicle membrane and cytosol. [provided by Alliance of Genome Resources, Apr 2022]

Submissions by phenotype

not specified Benign:1
Likely benign, criteria provided, single submitterclinical testingAmbry GeneticsNov 07, 2024This 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. -
