Thoracic aortic aneurysm or dissection

Gene: ABCC6

Red List (low evidence)

264800 AR pseudoxanthoma elasticum; 177850 AD psuedoxanthoma elasticum forme fruste - associated with ateriosclerosis and calcification. HGMD one variant associated with abdominal aortic aneurysm

Schulz et al (J Vasc Res 2005 42:424 PMID:16127278) looked for ABCC6 variants in a cohort of patients with abdominal aortic aneurysm. They identified 5 ABCC6 variants but frequency did not differ between cases and controls leading to the conclusion that none of these variants are not associated with AAA.

Mode of inheritance
BOTH monoallelic and biallelic, autosomal or pseudoautosomal

Not on the Inherited Cardiac Condition Genes panel reported in: Development of a Comprehensive Sequencing Assay for Inherited Cardiac Condition Genes, Pua et al, Journal of Cardiovascular Translational Research, online Feb 2016 (doi:10.​1007/​s12265-016-9673-5). The panel contains disease-causing, putatively pathogenic, research and phenocopy genes.

Red List (low evidence)

Pseudoxanthoma elasticum caused by ABCC6 deficiency in humans shows postnatally acquired elastic fibre fragmentation in the aorta, but does not typically show aneurysm (see ref above). No reports in the literature associating ABCC6 variants with thoracic aortic aneurysm.
