Genes affected
RDH11 (HGNC:17964): (retinol dehydrogenase 11) Enables NADP-retinol dehydrogenase activity. Involved in cellular detoxification of aldehyde and retinoid metabolic process. Acts upstream of or within retinal metabolic process. Located in endoplasmic reticulum membrane. [provided by Alliance of Genome Resources, Apr 2022]
GPHN (HGNC:15465): (gephyrin) This gene encodes a neuronal assembly protein that anchors inhibitory neurotransmitter receptors to the postsynaptic cytoskeleton via high affinity binding to a receptor subunit domain and tubulin dimers. In nonneuronal tissues, the encoded protein is also required for molybdenum cofactor biosynthesis. Mutations in this gene may be associated with the neurological condition hyperplexia and also lead to molybdenum cofactor deficiency. Numerous alternatively spliced transcript variants encoding different isoforms have been described; however, the full-length nature of all transcript variants is not currently known.

This variant is not present in population databases (gnomAD no frequency). This sequence change replaces serine, which is neutral and polar, with asparagine, which is neutral and polar, at codon 285 of the RDH11 protein (p.Ser285Asn). This variant also falls at the last nucleotide of exon 6, which is part of the consensus splice site for this exon. This variant has not been reported in the literature in individuals affected with RDH11-related conditions. ClinVar contains an entry for this variant (Variation ID: 1525683). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). Variants that disrupt the consensus splice site are a relatively common cause of aberrant splicing (PMID: 17576681, 9536098). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
