The c.1180A>C (p.I394L) alteration is located in exon 6 (coding exon 1) of the ZNF83 gene. This alteration results from a A to C substitution at nucleotide position 1180, causing the isoleucine (I) at amino acid position 394 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
