Genes affected

DHRS7 (HGNC:21524): (dehydrogenase/reductase 7) This gene encodes a member of the short-chain dehydrogenases/reductases (SDR) family, which has over 46,000 members. Members in this family are enzymes that metabolize many different compounds, such as steroid hormones, prostaglandins, retinoids, lipids and xenobiotics. [provided by RefSeq, Apr 2016]

PCNX4 (HGNC:20349): (pecanex 4) Predicted to be integral component of membrane. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Verdict is Uncertain_significance. Variant got 3 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.818

Apr 12, 2022

The c.502T>A (p.S168T) alteration is located in exon 4 (coding exon 4) of the DHRS7 gene. This alteration results from a T to A substitution at nucleotide position 502, causing the serine (S) at amino acid position 168 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
