The c.477A>C (p.E159D) alteration is located in exon 5 (coding exon 5) of the PHACTR2 gene. This alteration results from a A to C substitution at nucleotide position 477, causing the glutamic acid (E) at amino acid position 159 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
