Variant summary

Our verdict is Uncertain significance. Variant got 1 ACMG points: 2P and 1B. PM2BP4

The NM_001145971.2(RDH13):c.650G>A(p.Arg217Gln) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000136 in 1,613,962 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R217W) has been classified as Uncertain significance.

Genes affected

RDH13 (HGNC:19978): (retinol dehydrogenase 13) This gene encodes a mitochondrial short-chain dehydrogenase/reductase, which catalyzes the reduction and oxidation of retinoids. The encoded enzyme may function in retinoic acid production and may also protect the mitochondria against oxidative stress. Alternatively spliced transcript variants have been described.

Collection Method: clinical testing

The c.650G>A (p.R217Q) alteration is located in exon 5 (coding exon 5) of the RDH13 gene. This alteration results from a G to A substitution at nucleotide position 650, causing the arginine (R) at amino acid position 217 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
