The c.1145T>G (p.F382C) alteration is located in exon 6 (coding exon 1) of the ZNF83 gene. This alteration results from a T to G substitution at nucleotide position 1145, causing the phenylalanine (F) at amino acid position 382 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
