The c.1612G>T (p.G538C) alteration is located in exon 2 (coding exon 2) of the ZNF768 gene. This alteration results from a G to T substitution at nucleotide position 1612, causing the glycine (G) at amino acid position 538 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
