The c.1036C>T (p.R346W) alteration is located in exon 3 (coding exon 1) of the PRR30 gene. This alteration results from a C to T substitution at nucleotide position 1036, causing the arginine (R) at amino acid position 346 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
