Ambry Genetics

Nov 17, 2022

The c.461G>T (p.C154F) alteration is located in exon 2 (coding exon 2) of the PLEKHG4B gene. This alteration results from a G to T substitution at nucleotide position 461, causing the cysteine (C) at amino acid position 154 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
