Genes affected

COL5A1 (HGNC:2209): (collagen type V alpha 1 chain) This gene encodes an alpha chain for one of the low abundance fibrillar collagens. Fibrillar collagen molecules are trimers that can be composed of one or more types of alpha chains. Type V collagen is found in tissues containing type I collagen and appears to regulate the assembly of heterotypic fibers composed of both type I and type V collagen. This gene product is closely related to type XI collagen and it is possible that the collagen chains of types V and XI constitute a single collagen type with tissue-specific chain combinations. The encoded procollagen protein occurs commonly as the heterotrimer pro-alpha1(V)-pro-alpha1(V)-pro-alpha2(V). Mutations in this gene are associated with Ehlers-Danlos syndrome, types I and II. Alternative splicing of this gene results in multiple transcript variants. [provided by RefSeq, May 2013]

In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; Has not been previously published as pathogenic or benign to our knowledge; Occurs in the triple helical domain at the X position in the canonical Gly-X-Y repeat; although this variant may have an effect on normal protein folding and function, missense substitution at the {X/Y} position is not a common mechanism of disease (Symoens et al., 2012; Stenson et al., 2014) -

COL5A1 NM_000093.4 exon 27 p.Pro785Leu (c.2354C>T): This variant has not been reported in the literature and is present in 0.009% (3/30444) of South Asian alleles in the Genome Aggregation Database (http://gnomad.broadinstitute.org/variant/9-137666727-C-T). This variant is present in ClinVar (Variation ID:212949). Evolutionary conservation and computational predictive tools suggest that this variant may impact the protein. In summary, data on this variant is insufficient for disease classification. Therefore, the clinical significance of this variant is uncertain. -
