The c.78A>G (p.I26M) alteration is located in exon 2 (coding exon 2) of the PLEKHA8 gene. This alteration results from a A to G substitution at nucleotide position 78, causing the isoleucine (I) at amino acid position 26 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
