Genes affected
C1QTNF5 (HGNC:14344): (C1q and TNF related 5) This gene encodes a member of a family of proteins that function as components of basement membranes and may play a role in cell adhesion. Mutations in this gene have been associated with late-onset retinal degeneration. The protein may be encoded by either a bicistronic transcript including sequence from the upstream membrane frizzled-related protein gene (MFRP), or by a monocistronic transcript expressed from an internal promoter.

MFRP (HGNC:18121): (membrane frizzled-related protein) This gene encodes a member of the frizzled-related protein family. The encoded protein plays an important role in eye development and mutations in this gene have been associated with nanophthalmos, posterior microphthalmia, retinitis pigmentosa, foveoschisis, and optic disc drusen. The protein is encoded by a bicistronic transcript which also encodes C1q and tumor necrosis factor related protein 5 (C1QTNF5). [provided by RefSeq, Jun 2013]

This sequence change replaces serine, which is neutral and polar, with arginine, which is basic and polar, at codon 163 of the C1QTNF5 protein (p.Ser163Arg). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individuals with late-onset retinal degeneration (PMID: 12944416, 23289492, 29847639). It has also been observed to segregate with disease in related individuals. This variant is also known as c.686C>G. ClinVar contains an entry for this variant (Variation ID: 2126). 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 C1QTNF5 function (PMID: 24531000). For these reasons, this variant has been classified as Pathogenic. -

Most common pathogenic variant associated with late-onset retinal degeneration (Hayward et al., 2003; Stanton et al., 2017); Published functional studies demonstrate a damaging effect with aggregate formation in vitro and pathological effects in mice that were similar to patients with late-onset retinal degeneration (Hayward et al., 2003; Dinculescu et al., 2015); Not observed in large population cohorts (Lek et al., 2016); In silico analysis, which includes protein predictors and evolutionary conservation, supports that this variant does not alter protein structure/function; This variant is associated with the following publications: (PMID: 29721928, 31385385, 29555955, 12944416, 26513502, 26197217, 22110650, 24531000, 22892318, 21349921, 23289492) -
