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.808G>T (p.V270L) alteration is located in exon 7 (coding exon 7) of the DHRS7B gene. This alteration results from a G to T substitution at nucleotide position 808, causing the valine (V) at amino acid position 270 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
