Variant summary

Our verdict is Pathogenic. Variant got 14 ACMG points: 14P and 0B. PM5PP3_StrongPP5_Very_Strong

The NM_152443.3(RDH12):c.451C>G(p.His151Asp) variant causes a missense, splice region change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.000013 in 1,612,224 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. 1/1 splice prediction tools predict no significant impact on normal splicing. Variant has been reported in ClinVar as Pathogenic (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. H151N) has been classified as Likely pathogenic.

Genes affected

RDH12 (HGNC:19977): (retinol dehydrogenase 12) The protein encoded by this gene is an NADPH-dependent retinal reductase whose highest activity is toward 9-cis and all-trans-retinol. The encoded enzyme also plays a role in the metabolism of short-chain aldehydes but does not exhibit steroid dehydrogenase activity. Defects in this gene are a cause of Leber congenital amaurosis type 13 and Retinitis Pigmentosa 53. [provided by RefSeq, Sep 2015]

RDH12 links:

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.

Pathogenic, criteria provided, single submitter	clinical testing	Labcorp Genetics (formerly Invitae), Labcorp	Jan 16, 2024	This sequence change replaces histidine, which is basic and polar, with aspartic acid, which is acidic and polar, at codon 151 of the RDH12 protein (p.His151Asp). This variant is present in population databases (rs104894475, gnomAD 0.002%). This missense change has been observed in individuals with autosomal recessive RDH12-related conditions (PMID: 15322982, 17389517, 30718709). It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 2054). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. Experimental studies have shown that this missense change affects RDH12 function (PMID: 16269441). For these reasons, this variant has been classified as Pathogenic. -
