The c.1883T>C (p.L628P) alteration is located in exon 12 (coding exon 11) of the EXOC3L1 gene. This alteration results from a T to C substitution at nucleotide position 1883, causing the leucine (L) at amino acid position 628 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
