The c.961C>A (p.R321S) alteration is located in exon 2 (coding exon 2) of the ZNF768 gene. This alteration results from a C to A substitution at nucleotide position 961, causing the arginine (R) at amino acid position 321 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
