The c.661T>G (p.Y221D) alteration is located in exon 5 (coding exon 4) of the ZNF33A gene. This alteration results from a T to G substitution at nucleotide position 661, causing the tyrosine (Y) at amino acid position 221 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
