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]

ACMG classification

Our verdict: Uncertain_significance. The variant received 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.19415498).

Collection Method: clinical testing

The c.3697G>T (p.A1233S) alteration is located in exon 5 (coding exon 5) of the SGK223 gene. This alteration results from a G to T substitution at nucleotide position 3697, causing the alanine (A) at amino acid position 1233 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
