The c.689A>G (p.D230G) alteration is located in exon 2 (coding exon 2) of the EXOC3L4 gene. This alteration results from a A to G substitution at nucleotide position 689, causing the aspartic acid (D) at amino acid position 230 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
