Genes affected

DHRS7B (HGNC:24547): (dehydrogenase/reductase 7B) Predicted to enable DNA-binding transcription factor binding activity and transcription corepressor activity. Predicted to be involved in neutrophil differentiation. Predicted to act upstream of or within several processes, including brown fat cell differentiation; phosphatidylcholine biosynthetic process; and regulation of cold-induced thermogenesis. Located in membrane. [provided by Alliance of Genome Resources, Apr 2022]

The c.956A>C (p.E319A) alteration is located in exon 7 (coding exon 7) of the DHRS7B gene. This alteration results from a A to C substitution at nucleotide position 956, causing the glutamic acid (E) at amino acid position 319 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
