The c.1579A>C (p.T527P) alteration is located in exon 3 (coding exon 3) of the PWWP2A gene. This alteration results from a A to C substitution at nucleotide position 1579, causing the threonine (T) at amino acid position 527 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
