The c.943G>A (p.G315S) alteration is located in exon 7 (coding exon 7) of the PHF21B gene. This alteration results from a G to A substitution at nucleotide position 943, causing the glycine (G) at amino acid position 315 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
