The c.2851G>T (p.V951L) alteration is located in exon 20 (coding exon 18) of the PLEKHA6 gene. This alteration results from a G to T substitution at nucleotide position 2851, causing the valine (V) at amino acid position 951 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
