The c.1016T>G (p.F339C) alteration is located in exon 5 (coding exon 4) of the ZNF350 gene. This alteration results from a T to G substitution at nucleotide position 1016, causing the phenylalanine (F) at amino acid position 339 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
