Collection Method: clinical testing

The c.889G>A (p.D297N) alteration is located in exon 5 (coding exon 5) of the DHRS13 gene. This alteration results from a G to A substitution at nucleotide position 889, causing the aspartic acid (D) at amino acid position 297 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
