The c.1646C>T (p.P549L) alteration is located in exon 11 (coding exon 10) of the EXOC3L1 gene. This alteration results from a C to T substitution at nucleotide position 1646, causing the proline (P) at amino acid position 549 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
