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 GeneticsMar 02, 2023The c.920G>A (p.C307Y) alteration is located in exon 4 (coding exon 3) of the SIPA1 gene. This alteration results from a G to A substitution at nucleotide position 920, causing the cysteine (C) at amino acid position 307 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
