Feb 15, 2023

The c.631G>A (p.A211T) alteration is located in exon 5 (coding exon 3) of the EXD2 gene. This alteration results from a G to A substitution at nucleotide position 631, causing the alanine (A) at amino acid position 211 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
