The c.764A>G (p.N255S) alteration is located in exon 3 (coding exon 2) of the TCAF2 gene. This alteration results from a A to G substitution at nucleotide position 764, causing the asparagine (N) at amino acid position 255 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
