Genes affected
RDH14 (HGNC:19979): (retinol dehydrogenase 14) Enables NADP-retinol dehydrogenase activity. Involved in osteoblast differentiation. Located in cytosol; endoplasmic reticulum; and nucleoplasm. [provided by Alliance of Genome Resources, Apr 2022]
NT5C1B-RDH14 (HGNC:38831): (NT5C1B-RDH14 readthrough) This locus represents naturally occurring read-through transcription between the neighboring NT5C1B (5'-nucleotidase, cytosolic IB) and RDH14 (retinol dehydrogenase 14) genes on chromosome 2. Alternative splicing results in multiple transcript variants, one of which encodes a fusion protein that shares sequence identity with the products of each individual gene.

The c.854C>T (p.T285I) alteration is located in exon 2 (coding exon 2) of the RDH14 gene. This alteration results from a C to T substitution at nucleotide position 854, causing the threonine (T) at amino acid position 285 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
