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.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 16, 2022The c.314G>T (p.R105L) alteration is located in exon 3 (coding exon 3) of the RDH13 gene. This alteration results from a G to T substitution at nucleotide position 314, causing the arginine (R) at amino acid position 105 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
