The c.1478C>T (p.P493L) alteration is located in exon 9 (coding exon 9) of the DUS3L gene. This alteration results from a C to T substitution at nucleotide position 1478, causing the proline (P) at amino acid position 493 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
