Genes affected

RASAL2 (HGNC:9874): (RAS protein activator like 2) This gene encodes a protein that contains the GAP-related domain (GRD), a characteristic domain of GTPase-activating proteins (GAPs). GAPs function as activators of Ras superfamily of small GTPases. The protein encoded by this gene is able to complement the defective RasGAP function in a yeast system. Two alternatively spliced transcript variants of this gene encoding distinct isoforms have been reported. [provided by RefSeq, Jul 2008]

Collection Method: clinical testing

The c.185G>C (p.S62T) alteration is located in exon 1 (coding exon 1) of the RASAL2 gene. This alteration results from a G to C substitution at nucleotide position 185, causing the serine (S) at amino acid position 62 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
