Variant summary

Our verdict is Benign. The variant received -7 ACMG points: 1P and 8B. PP3BS1BS2

The NM_000393.5(COL5A2):​c.3178C>T​(p.Arg1060Trp) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000843 in 1,613,910 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R1060Q) has been classified as Uncertain significance.

Genes affected
COL5A2 (HGNC:2210): (collagen type V alpha 2 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. Mutations in this gene are associated with Ehlers-Danlos syndrome, types I and II. [provided by RefSeq, Jul 2008]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -7 ACMG points.

PP3
MetaRNN computational evidence supports a deleterious effect, 0.769
BS1
Variant frequency is greater than expected in population nfe. GnomAd4 allele frequency = 0.0000788 (12/152220) while in subpopulation NFE AF = 0.000118 (8/68024). AF 95% confidence interval is 0.0000584. There are 0 homozygotes in GnomAd4. There are 5 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check.
BS2
High AC in GnomAd4 at 12 AD gene.
