Genes affected

SIPA1L2 (HGNC:23800): (signal induced proliferation associated 1 like 2) This gene encodes a member of the signal-induced proliferation-associated 1 like family. Members of this family contain a GTPase activating domain, a PDZ domain and a C-terminal coiled-coil domain with a leucine zipper. A similar protein in rat acts as a GTPases for the small GTPase Rap.

Ambry Genetics

Nov 17, 2023

The c.4615A>C (p.M1539L) alteration is located in exon 16 (coding exon 16) of the SIPA1L2 gene. This alteration results from a A to C substitution at nucleotide position 4615, causing the methionine (M) at amino acid position 1539 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
