Description

The p.V2868D variant (also known as c.8603T>A), located in coding exon 65 of the FBN1 gene, results from a T to A substitution at nucleotide position 8603. The valine at codon 2868 is replaced by aspartic acid, an amino acid with highly dissimilar properties. This variant was not reported in population based cohorts in the following databases: Database of Single Nucleotide Polymorphisms (dbSNP), NHLBI Exome Sequencing Project (ESP), and 1000 Genomes Project. In the ESP, this variant was not observed in 6495 samples (12990 alleles) with coverage at this position. This amino acid position is poorly conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this variant remains unclear.
