The c.2807G>T (p.C936F) alteration is located in exon 3 (coding exon 1) of the ZNF518B gene. This alteration results from a G to T substitution at nucleotide position 2807, causing the cysteine (C) at amino acid position 936 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
