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 GeneticsJun 05, 2024The c.467C>T (p.S156L) alteration is located in exon 2 (coding exon 1) of the SIPA1 gene. This alteration results from a C to T substitution at nucleotide position 467, causing the serine (S) at amino acid position 156 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
