The c.1042G>A (p.D348N) alteration is located in exon 3 (coding exon 1) of the PRR30 gene. This alteration results from a G to A substitution at nucleotide position 1042, causing the aspartic acid (D) at amino acid position 348 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
