Genetic Variant SDR39U1:p.Ala247Thr (chr14-24440226-C-T) – ACMG Classification: Likely_benign (-4 pts)

Variant summary

Our verdict is Likely benign. The variant received -4 ACMG points: 0P and 4B. BP4_Strong

The NM_020195.3(SDR39U1):c.739G>A(p.Ala247Thr) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000108 in 1,613,964 control chromosomes in the GnomAD database, including 1 homozygotes. In-silico tool predicts a benign outcome for this variant. 15/20 in silico tools predict a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. A247S) has been classified as Uncertain significance.

Genes affected

SDR39U1 (HGNC:20275): (short chain dehydrogenase/reductase family 39U member 1) This gene encodes a member of the short-chain dehydrogenases/reductases (SDR) superfamily, which includes both classical and extended types. The encoded protein represents an extended type, with similarity to epimerases. Alternatively spliced transcript variants that encode different protein isoforms have been described. [provided by RefSeq, Mar 2014]

SDR39U1 links:

KHNYN (HGNC:20166): (KH and NYN domain containing) The protein encoded by this gene contains a ribonuclease NYN domain and belongs to the N4BP1 family. The protein is a cofactor for the zinc finger antiviral protein (ZAP protein) which targets viral RNA for degradation and restricts SARS-CoV-2 infection. [provided by RefSeq, Sep 2021]
