Genes affected

ADAMTS2 (HGNC:218): (ADAM metallopeptidase with thrombospondin type 1 motif 2) This gene encodes a member of the ADAMTS (a disintegrin and metalloproteinase with thrombospondin motifs) protein family. Members of the family share several distinct protein modules, including a propeptide region, a metalloproteinase domain, a disintegrin-like domain, and a thrombospondin type 1 (TS) motif. Individual members of this family differ in the number of C-terminal TS motifs, and some have unique C-terminal domains. The encoded preproprotein is proteolytically processed to generate the mature procollagen N-proteinase. This proteinase excises the N-propeptide of the fibrillar procollagens types I-III and type V. Mutations in this gene cause Ehlers-Danlos syndrome type VIIC, a recessively inherited connective-tissue disorder. Alternative splicing results in multiple transcript variants, at least one of which encodes an isoform that is proteolytically processed. [provided by RefSeq, Feb 2016]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -9 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.011239171).

BP6

Variant 5-179125038-C-T is Benign according to our data. Variant chr5-179125038-C-T is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 469674.

BS1

Variant frequency is greater than expected in population amr. GnomAdExome4 allele frequency = 0.000357 (520/1456470) while in subpopulation AMR AF = 0.00508 (221/43484). AF 95% confidence interval is 0.00453. There are 1 homozygotes in GnomAdExome4. There are 214 alleles in the male GnomAdExome4 subpopulation. Median coverage is 38. This position passed quality control check.
