Collection Method: clinical testing

The c.631G>C (p.E211Q) alteration is located in exon 5 (coding exon 5) of the DHRS7C gene. This alteration results from a G to C substitution at nucleotide position 631, causing the glutamic acid (E) at amino acid position 211 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
