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]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -8 ACMG points.

BS1
Variant frequency is greater than expected in population sas. GnomAdExome4 allele frequency = 0.0000171 (25/1461136) while in subpopulation SAS AF = 0.000278 (24/86210). AF 95% confidence interval is 0.000192. There are 0 homozygotes in GnomAdExome4. There are 20 alleles in the male GnomAdExome4 subpopulation. Median coverage is 30. This position passed quality control check.
BS2
High AC in GnomAdExome4 at 25 AD gene.
