The c.1144G>A (p.D382N) alteration is located in exon 1 (coding exon 1) of the OXER1 gene. This alteration results from a G to A substitution at nucleotide position 1144, causing the aspartic acid (D) at amino acid position 382 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
