The c.148C>A (p.P50T) alteration is located in exon 3 (coding exon 3) of the PDXDC1 gene. This alteration results from a C to A substitution at nucleotide position 148, causing the proline (P) at amino acid position 50 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
