Ambry Genetics

Sep 01, 2021

The c.302C>A (p.T101K) alteration is located in exon 3 (coding exon 1) of the PLEKHG1 gene. This alteration results from a C to A substitution at nucleotide position 302, causing the threonine (T) at amino acid position 101 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
