Variant summary
Our verdict is Pathogenic. Variant got 12 ACMG points: 12P and 0B. PM1PM2PM5PP2PP3_StrongPP5
The NM_000090.4(COL3A1):c.1655G>A(p.Gly552Glu) variant causes a missense change. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Pathogenic (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. G552R) has been classified as Pathogenic.

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]

ACMG classification
Classification made for transcript
Verdict is Pathogenic. Variant got 12 ACMG points.
PM1
In a hotspot region, there are 3 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 0 benign, 6 uncertain in NM_000090.4
PM2
Very rare variant in population databases, with high coverage;
PM5
Other missense variant is known to change same aminoacid residue: Variant chr2-188996170-G-A is described in ClinVar as [Pathogenic]. Clinvar id is 847405.Status of the report is criteria_provided_single_submitter, 1 stars.
PP2
Missense variant in gene, where missense usually causes diseases (based on misZ statistic), COL3A1. . Gene score misZ 4.0879 (greater than the threshold 3.09). Trascript score misZ 4.5995 (greater than threshold 3.09). GenCC has associacion of gene with Ehlers-Danlos syndrome, vascular type, autosomal dominant Ehlers-Danlos syndrome, vascular type, polymicrogyria with or without vascular-type Ehlers-Danlos syndrome.
PP3
MetaRNN computational evidence supports a deleterious effect, 0.994
PP5
Variant 2-188996171-G-A is Pathogenic according to our data. Variant chr2-188996171-G-A is described in ClinVar as [Pathogenic]. Clinvar id is 17211.Status of the report is no_assertion_criteria_provided, 0 stars.
