Genes affected

COL3A1 (HGNC:2201): (collagen type III alpha 1 chain) This gene encodes the pro-alpha1 chains of type III collagen, a fibrillar collagen that is found in extensible connective tissues such as skin, lung, uterus, intestine and the vascular system, frequently in association with type I collagen. Mutations in this gene are associated with Ehlers-Danlos syndrome type IV, and with aortic and arterial aneurysms. [provided by R. Dalgleish, Feb 2008]

Computational evidence support a benign effect (BayesDel_noAF=-0.43).

BP6

Variant 2-188996175-T-A is Benign according to our data. Variant chr2-188996175-T-A is described in ClinVar as Benign/Likely_benign. ClinVar VariationId is 199696.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

BP7

Synonymous conserved (PhyloP=0.057 with no splicing effect.

BS1

Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.00408 (620/151826) while in subpopulation AFR AF = 0.0139 (577/41404). AF 95% confidence interval is 0.013. There are 5 homozygotes in GnomAd4. There are 286 alleles in the male GnomAd4 subpopulation. Median coverage is 30. This position passed quality control check.

BS2

High Homozygotes in GnomAd4 at 5 AD,AR gene
