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]
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. [provided by RefSeq, Jul 2008]

ACMG classification

Classification was made for transcript

Our verdict: Pathogenic. The variant received 11 ACMG points.

PM1
In a hotspot region, there are 2 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 1 benign, 10 uncertain in NM_152443.3
PP2
Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 53 curated pathogenic missense variants (we use a threshold of 10). The gene has 2 curated benign missense variants. Gene score misZ: -0.14222 (below the threshold of 3.09). Trascript score misZ: 0.34257 (below the threshold of 3.09). GenCC associations: The gene is linked to RDH12-related recessive retinopathy, retinitis pigmentosa, Leber congenital amaurosis 13, Leber congenital amaurosis.
PP5
Variant 14-67725206-C-A is Pathogenic according to our data. Variant chr14-67725206-C-A is described in ClinVar as Pathogenic/Likely_pathogenic. ClinVar VariationId is 2055.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
