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.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 16, 2024The c.4582A>G (p.T1528A) alteration is located in exon 16 (coding exon 16) of the SIPA1L2 gene. This alteration results from a A to G substitution at nucleotide position 4582, causing the threonine (T) at amino acid position 1528 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
