Mode of inheritance
X-LINKED: hemizygous mutation in males, biallelic mutations in females

Not on the Inherited Cardiac Condition Genes panel for Familial aortic anuerysm 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.

Menkes disease- despite high frequency of ascending aneurysm formation in the "blotchy" mouse (PMID: 3385878), predominant feature in humans is vascular tortuosity rather than true aneurysm formation with only a few case reports in the literature (brachial artery, PMID: 16939759; iliac artery, PMID: 19522551). In a different study of 95 affected individuals, 4 (4.2%) had major congenital heart defects with no evidence of aortic dilatation on echocardiography (PMID: 22134099). Therefore, there is inadequate information at present linking ATP7A to human thoracic aortic disease.

Occipital horn syndrome- Linked to aneurysm of abdominal vessels, hepatic artery, and splenic artery (PMID: 15981243) but again no evidence of thoracic aortic disease.
