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

Feb 10, 2023

The c.4888C>A (p.L1630M) alteration is located in exon 19 (coding exon 19) of the SIPA1L2 gene. This alteration results from a C to A substitution at nucleotide position 4888, causing the leucine (L) at amino acid position 1630 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
