The c.128C>A (p.T43K) alteration is located in exon 2 (coding exon 1) of the PRR15 gene. This alteration results from a C to A substitution at nucleotide position 128, causing the threonine (T) at amino acid position 43 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
