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]

Ambry Genetics

Oct 26, 2022

The c.1858C>T (p.P620S) alteration is located in exon 20 (coding exon 20) of the RASA3 gene. This alteration results from a C to T substitution at nucleotide position 1858, causing the proline (P) at amino acid position 620 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
