Thoracic aortic aneurysm and dissectionGene: THSD4
Comment on list classification: New gene added by Zornitza Stark (Australian Genomics). There is no phenotypes associated with this gene in OMIM or Gene2Phenotype. There is enough evidence to support a gene-disease association. This gene should be rated Green at the next review.

5 heterozygous variants in THSD4 (two lead to a premature termination codon) found in 5 families with TAAD. Variants segregated with disease in other family members. THSD4 encodes ADAMTSL6, a microfibril-associated protein that promotes fibrillin-1 matrix assembly. The THSD4 variants studied lead to haploinsufficiency or impaired assembly of fibrillin-1 microfibrils. Thsd4+/- mice showed progressive dilation of the thoracic aorta. Histologic examination of aortic samples from a patient carrying a THSD4 variant and from Thsd4+/- mice, revealed typical medial degeneration and diffuse disruption of extracellular matrix.
