The c.682C>A (p.P228T) alteration is located in exon 2 (coding exon 2) of the EXOC3L4 gene. This alteration results from a C to A substitution at nucleotide position 682, causing the proline (P) at amino acid position 228 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
