The c.1306C>A (p.P436T) alteration is located in exon 10 (coding exon 10) of the THUMPD2 gene. This alteration results from a C to A substitution at nucleotide position 1306, causing the proline (P) at amino acid position 436 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
