Genes affected
SIPA1 (HGNC:10885): (signal-induced proliferation-associated 1) The product of this gene is a mitogen induced GTPase activating protein (GAP). It exhibits a specific GAP activity for Ras-related regulatory proteins Rap1 and Rap2, but not for Ran or other small GTPases. This protein may also hamper mitogen-induced cell cycle progression when abnormally or prematurely expressed. It is localized to the perinuclear region. Two alternatively spliced variants encoding the same isoform have been characterized to date. [provided by RefSeq, Jul 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 11, 2022The c.237C>G (p.S79R) alteration is located in exon 2 (coding exon 1) of the SIPA1 gene. This alteration results from a C to G substitution at nucleotide position 237, causing the serine (S) at amino acid position 79 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
