Ambry Genetics

Aug 12, 2022

The c.500A>G (p.Y167C) alteration is located in exon 4 (coding exon 2) of the PLEKHG1 gene. This alteration results from a A to G substitution at nucleotide position 500, causing the tyrosine (Y) at amino acid position 167 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
