Ehlers Danlos syndrome with a likely monogenic cause
Gene: MYLKComment on phenotypes: Previous phenotypes:
Aortic aneurysm, familial thoracic 7, 613780;FTAA;Familial thoracic aortic aneurysm;aortic dissection with or without aortic aneurysmCreated: 18 Mar 2021, 2:28 p.m. | Last Modified: 18 Mar 2021, 2:28 p.m.
Panel Version: 2.55
This gene is associated with Familial thoracic aortic aneurysm. Although patients with variants in this gene may present with EDS features it was decided following discussion in the GMS musculoskeletal specialist test group Webex on 2019-06-04 it to keep this gene amber. If more evidence of an overlap in phenotypes becomes available the rating can be reviewed.Created: 14 Aug 2019, 2:19 p.m. | Last Modified: 14 Aug 2019, 2:19 p.m.

This gene was part of an initial gene list collated by Duncan Baker, Sheffield Diagnostic Genetics Service, January 2019 on behalf of the GMS Musculoskeletal Specialist Group; Gene symbol submitted: MYLK; Suggested initial gene rating: greenCreated: 3 Apr 2019, 3:41 p.m.
Lab experience indicates that MYLK pathogenic mutations can present with EDS features.Created: 24 Jan 2019, 11:45 a.m.
Mode of inheritance
MONOALLELIC, autosomal or pseudoautosomal, NOT imprinted
Phenotypes
aortic dissection with or without aortic aneurysm
Variants in this GENE are reported as part of current diagnostic practice
There is a clear gene-disease association but in view of the relatively discrete vascular phenotype, this gene would be best placed on the FTAAD panel rather than as a differential diagnosis for those with connective tissue disease. Those with a vascular phenotype in addition would be offered the FTAAD panel in addition. D/W Neeti Ghali, EDS Specialist Clinic who is in agreement.Created: 25 Jul 2017, 12:59 p.m.
Mode of inheritance
MONOALLELIC, autosomal or pseudoautosomal, imprinted status unknown
Phenotypes
Aortic aneurysm, familial thoracic 7 613780

Comment on list classification: Changed from Green to Amber based due to the relatively discrete vascular phenotypeCreated: 25 Jul 2017, 12:59 p.m.
Comment on list classification: changed status from Red to green due to external review and further literature searchCreated: 10 Jul 2017, 3:26 p.m.
Comment on publications: Added publications to support association to FTAACreated: 10 Jul 2017, 3:24 p.m.
Comment on publications: 2 unrelated families reported PMID:21055718Created: 10 Jul 2017, 3:19 p.m.
Comment on phenotypes: Removed 'Marfan Syndrome, Thoracic Aortic Aneurysm & Dissection (TAAD), and Related Disorders' as this comes from the name of the sequencing panel from EGL Genetics. Gene on panel due to associated with non-syndromic Thoracic Aortic Aneurysm & Dissection (TAAD), need to check with clinical team team if this gene should remain on this panel based on update to eligibility statement.Created: 4 May 2017, 10:09 a.m.
