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.3902A>G (p.H1301R) alteration is located in exon 5 (coding exon 5) of the SGK223 gene. This alteration results from a A to G substitution at nucleotide position 3902, causing the histidine (H) at amino acid position 1301 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
