Genes affected
RASA3 (HGNC:20331): (RAS p21 protein activator 3) This gene encodes a protein that binds inositol 1,3,4,5-tetrakisphosphate and stimulates the GTPase activity of Ras p21. This protein functions as a negative regulator of the Ras signalling pathway. It is localized to the cell membrane via a pleckstrin homology (PH) domain in the C-terminal region. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Mar 2016]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 01, 2023The c.2221A>G (p.M741V) alteration is located in exon 22 (coding exon 22) of the RASA3 gene. This alteration results from a A to G substitution at nucleotide position 2221, causing the methionine (M) at amino acid position 741 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
