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.

Feb 03, 2023

The c.4910G>A (p.G1637D) alteration is located in exon 19 (coding exon 19) of the SIPA1L2 gene. This alteration results from a G to A substitution at nucleotide position 4910, causing the glycine (G) at amino acid position 1637 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
