The c.961G>C (p.V321L) alteration is located in exon 8 (coding exon 8) of the ZFP28 gene. This alteration results from a G to C substitution at nucleotide position 961, causing the valine (V) at amino acid position 321 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
