The c.577G>A (p.V193I) 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 577, causing the valine (V) at amino acid position 193 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
