The c.1336C>A (p.P446T) alteration is located in exon 12 (coding exon 12) of the NDC1 gene. This alteration results from a C to A substitution at nucleotide position 1336, causing the proline (P) at amino acid position 446 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
