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 -13 ACMG points.

BP4

Computational evidence support a benign effect (BayesDel_noAF=-0.9).

BP6

Variant 9-134728821-G-A is Benign according to our data. Variant chr9-134728821-G-A is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 136925.

BS1

Variant frequency is greater than expected in population amr. GnomAd4 allele frequency = 0.000374 (57/152206) while in subpopulation AMR AF = 0.000785 (12/15288). AF 95% confidence interval is 0.000452. There are 0 homozygotes in GnomAd4. There are 37 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check.

BS2

High AC in GnomAd4 at 57 AD gene.
