Genes affected
COL5A2 (HGNC:2210): (collagen type V alpha 2 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. Mutations in this gene are associated with Ehlers-Danlos syndrome, types I and II. [provided by RefSeq, Jul 2008]

Review Status: criteria provided, single submitter
Collection Method: clinical testing

Variant summary: The COL5A2 c.1535T>C (p.Val512Ala) variant involves the alteration of a conserved nucleotide, resulting in a missense substitution. The variant does not lie within a known functional domain (InterPro) and 2/4 in silico tools predict a benign outcome for this variant (SNPs&GO not captured due to low reliability index). This variant was found in the large control database ExAC at a frequency of 0.0182311 (2213/121386 control chromosomes [34 homozygotes]), which is approximately 14585 times the estimated maximal expected allele frequency of a pathogenic COL5A2 variant (0.0000013), suggesting this variant is likely a benign polymorphism. In addition, multiple clinical diagnostic laboratories/reputable databases classified this variant as benign. To our knowledge, the variant of interest has not been reported in affected individuals via publications, nor has it been evaluated for functional impact by in vivo/vitro studies. Taken together, this variant is classified as benign. -

Significance: Benign
Review Status: criteria provided, single submitter
Collection Method: clinical testing

This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score and internal cut-off values, a variant classified as benign is not then subjected to further curation. The score for this variant resulted in a classification of benign for this disease. -

Significance: Benign
Review Status: criteria provided, single submitter
Collection Method: clinical testing

This alteration is classified as benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
