The c.511G>A (p.E171K) alteration is located in exon 2 (coding exon 2) of the PLEKHG4B gene. This alteration results from a G to A substitution at nucleotide position 511, causing the glutamic acid (E) at amino acid position 171 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
