The c.888C>A (p.N296K) alteration is located in exon 2 (coding exon 2) of the DPCR1 gene. This alteration results from a C to A substitution at nucleotide position 888, causing the asparagine (N) at amino acid position 296 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
