Familial thoracic aortic aneurysm and aortic dissection Uncertain:3
The p.S1533F variant (also known as c.4598C>T), located in coding exon 32 of the MYH11 gene, results from a C to T substitution at nucleotide position 4598. The serine at codon 1533 is replaced by phenylalanine, an amino acid with highly dissimilar properties. This amino acid position is conserved. In addition, the in silico prediction for this alteration is inconclusive. Based on the available evidence, the clinical significance of this alteration remains unclear. -
This missense variant replaces serine with phenylalanine at codon 1540 of the MYH11 protein. Computational prediction is inconclusive regarding the impact of this variant on protein structure and function (internally defined REVEL score threshold 0.5 < inconclusive < 0.7, PMID: 27666373). To our knowledge, functional studies have not been reported for this variant. This variant has not been reported in individuals affected with MYH11-related disorders in the literature. This variant has been identified in 4/251372 chromosomes in the general population by the Genome Aggregation Database (gnomAD). The available evidence is insufficient to determine the role of this variant in disease conclusively. Therefore, this variant is classified as a Variant of Uncertain Significance. -
