The c.644T>A (p.L215Q) alteration is located in exon 8 (coding exon 8) of the PLEKHA5 gene. This alteration results from a T to A substitution at nucleotide position 644, causing the leucine (L) at amino acid position 215 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
