The c.71A>C (p.K24T) alteration is located in exon 3 (coding exon 2) of the ZNF740 gene. This alteration results from a A to C substitution at nucleotide position 71, causing the lysine (K) at amino acid position 24 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
