The c.347C>G (p.T116R) alteration is located in exon 3 (coding exon 2) of the ZNF446 gene. This alteration results from a C to G substitution at nucleotide position 347, causing the threonine (T) at amino acid position 116 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
