Thoracic aortic aneurysm or dissection v1.127 MYLK Arina Puzriakova Phenotypes for gene: MYLK were changed from Aortic aneurysm, familial thoracic 7, 613780; Aortic aneurysm, familial thoracic 7 (613780) to Aortic aneurysm, familial thoracic 7, OMIM:613780
Thoracic aortic aneurysm or dissection v1.90 MYLK Rebecca Whittington commented on gene: MYLK: 613780 FTAAD; non-syndromic; well characterised gene
Thoracic aortic aneurysm or dissection v1.89 MFAP5 Rebecca Whittington commented on gene: MFAP5: Barbier et al 2014 Am J Hum Genet 95:736 PMID:25434006 describe one missense variant c.62G>T (p.Trp21Leu) (MAF 0.0036% 10 alleles - quite high) and one nonsense variant (in final exon) c.472C>T (p.Arg158*) (MAF 0.0045% 11 alleles) in patients with syndromic/non-syndromic thoracic aortic aneurysm and dissections and no previous genetic diagnoisis. The nonsense variant segregates in 4 affected family members (also present in one unaffected 83 year-old and two family members with ambiguous phenotypes - incomplete penetrance?) and the missense variant in two affected family members (plus one younger family member with ambigous phenotype). Functional studies on aortic tissue (following surgery) from the missense variant showed disorganisation of the tunica media with loss of smooth muscle cells and showed enhanced TGF-b signaling in patient compared to healthy aorta. Schubert et al 2016 Am J Med Genet A 170A:1288 PMID:26854089 indentified an additional MFAP5 variant in a TAA cohort - patient also as an MYLK variant. Both missense and classified as VUS. MFAP5 variant is c.341G>A p.Arg114Gln (MAF ASJ 0.34% (56 alleles)) and has stronger supporting BI than the MYLK variant.
