Variant summary
Our verdict is Uncertain significance. Variant got 5 ACMG points: 5P and 0B. PVS1_ModeratePM2PP5
The NM_000090.4(COL3A1):c.951_951+14del variant causes a splice donor, splice donor 5th base, coding sequence, intron change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. Variant has been reported in ClinVar as Pathogenic (no stars). Synonymous variant affecting the same amino acid position (i.e. A316A) has been classified as Uncertain significance.

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 Uncertain_significance. Variant got 5 ACMG points.
PVS1
?
Splicing variant, NOT destroyed by nmd, known LOF gene, truncates exone, which is 0.006021359 fraction of the gene. Cryptic splice site detected, with MaxEntScore 8, offset of -35, new splice context is: ctgGTgagc. Cryptic site results in frameshift change. If cryptic site found is not functional and variant results in exon loss, it results in inframe change.
PM2
?
Very rare variant in population databases, with high coverage;
PP5
?
Variant 2-188991716-GGCTGCAGTGAGTATA-G is Pathogenic according to our data. Variant chr2-188991716-GGCTGCAGTGAGTATA-G is described in ClinVar as [Pathogenic]. Clinvar id is 101111.Status of the report is no_assertion_criteria_provided, 0 stars.
