The c.1024A>G (p.N342D) alteration is located in exon 10 (coding exon 10) of the PLEKHA5 gene. This alteration results from a A to G substitution at nucleotide position 1024, causing the asparagine (N) at amino acid position 342 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
