Genes affected

PRAG1 (HGNC:25438): (PEAK1 related, kinase-activating pseudokinase 1) This gene encodes an enzyme that belongs to the tyrosine protein kinase family. A similar protein in rat binds to Rho family GTPase 2 (Rnd2) and regulates neurite outgrowth via activation of Ras homolog gene family, member A (RhoA). [provided by RefSeq, Mar 2014]

The c.3828A>C (p.R1276S) alteration is located in exon 5 (coding exon 5) of the SGK223 gene. This alteration results from a A to C substitution at nucleotide position 3828, causing the arginine (R) at amino acid position 1276 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
