Aortopathy_Connective Tissue Disorders v0.123 ELN Zornitza Stark Marked gene: ELN as ready
Aortopathy_Connective Tissue Disorders v0.123 ELN Zornitza Stark Gene: eln has been classified as Green List (High Evidence).
Aortopathy_Connective Tissue Disorders v0.123 ELN Zornitza Stark Classified gene: ELN as Green List (high evidence)
Aortopathy_Connective Tissue Disorders v0.123 ELN Zornitza Stark Gene: eln has been classified as Green List (High Evidence).
Aortopathy_Connective Tissue Disorders v0.106 ELN Belinda Chong gene: ELN was added
gene: ELN was added to Aortopathy_Connective Tissue Disorders. Sources: Other
Mode of inheritance for gene: ELN was set to MONOALLELIC, autosomal or pseudoautosomal, imprinted status unknown
Publications for gene: ELN were set to 27866049; 31560829; 19844261; 19844261
Phenotypes for gene: ELN were set to Cutis laxa 123700; Supravalvar aortic stenosis 185500
Review for gene: ELN was set to GREEN
Added comment: >3 families with Cutis laxa or Supravalvar aortic stenosis.

PMID: 30071989
Assertion made by the Aortopathy working group. So far there is no evidence that patients with ELN mutations present with aortic dissection or progressive aortic enlargement. Functional evidence, however, supports a role for ELN in HTAAD. ELN mutations cause AD cutis laxa syndrome, a disease with low risk for thoracic aortic disease and primarily diagnosed based on non-vascular features

Aortopathy_Connective Tissue Disorders v0.30 SMAD4 Paul De Fazio changed review comment from: "Limited evidence" for association with aortic dilatation/dissection by ClinGen:

"Eight genes scored as moderate (EFEMP2) or limited (ELN, FBN2, FLNA, NOTCH1,
SLC2A10, SMAD4, and SKI) for association with HTAAD. These genes are a heterogeneous group for which the evidence was often difficult to assess...the evidence, therefore, for their association with a presentation of aortic dilatation and/or dissection is often rather lacking. The other common feature of these conditions is that there is no robust evidence of progression to aortic dissection."

The ClinGen review of SMAD4, viewable in the supplementary material, dates to 22/12/2016 and so does not account for the reported individuals in PMID 30809044.

Green in PanelApp UK although with quite a few Amber reviews.

There is an association between people with with SMAD4 variants and aortic dissection (PMID 25931195).; to: "Limited evidence" for association with aortic dilatation/dissection by ClinGen:

Given this more recent data Green is appropriate.
