Variant summary
Our verdict is Benign. The variant received -7 ACMG points: 0P and 7B. BP4_ModerateBP6BS2
The NM_000093.5(COL5A1):c.5348G>A(p.Arg1783His) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000281 in 1,461,306 control chromosomes in the GnomAD database, including 1 homozygotes. In-silico tool predicts a benign outcome for this variant. 16/22 in silico tools predict a benign 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. R1783P) has been classified as Uncertain significance.

Familial thoracic aortic aneurysm and aortic dissection Uncertain:1
The p.R1783H variant (also known as c.5348G>A), located in coding exon 65 of the COL5A1 gene, results from a G to A substitution at nucleotide position 5348. The arginine at codon 1783 is replaced by histidine, an amino acid with highly similar properties. This amino acid position is well conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Based on the available evidence, the clinical significance of this alteration remains unclear. -
Ehlers-Danlos syndrome, classic type Uncertain:1
COL5A1 NM_000093.4 exon65 p.Arg1783His (c.5348G>A): This variant not been reported in the literature, but is present in 9/33572 Latino individuals in the Genome Aggregation Database (http://gnomad.broadinstitute.org/rs777045810). Evolutionary conservation and computational predictive tools suggest that this variant may not impact the protein. Of note, 7 other species have the variant Histidine (His) at this position, further suggesting that this variant may be tolerated. In summary, data on this variant is insufficient for disease classification. Therefore, the clinical significance of this variant is uncertain. -
