The c.1004G>A (p.C335Y) alteration is located in exon 5 (coding exon 4) of the ZNF667 gene. This alteration results from a G to A substitution at nucleotide position 1004, causing the cysteine (C) at amino acid position 335 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
