The c.1235T>C (p.V412A) alteration is located in exon 3 (coding exon 1) of the PRR30 gene. This alteration results from a T to C substitution at nucleotide position 1235, causing the valine (V) at amino acid position 412 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
