The c.62A>G (p.Y21C) alteration is located in exon 1 (coding exon 1) of the ZNF609 gene. This alteration results from a A to G substitution at nucleotide position 62, causing the tyrosine (Y) at amino acid position 21 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
