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 GeneticsDec 16, 2022The c.5017C>T (p.R1673W) alteration is located in exon 20 (coding exon 20) of the SIPA1L2 gene. This alteration results from a C to T substitution at nucleotide position 5017, causing the arginine (R) at amino acid position 1673 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
