Pulmonary Arterial Hypertension v1.33 SMAD4 Zornitza Stark Phenotypes for gene: SMAD4 were changed from Juvenile polyposis/hereditary hemorrhagic telangiectasia syndrome MIM#175050; Pulmonary arterial hypertension to Pulmonary arterial hypertension MONDO:0015924, SMAD4-related
Pulmonary Arterial Hypertension v1.32 SMAD4 Zornitza Stark Tag disputed tag was added to gene: SMAD4.
Pulmonary Arterial Hypertension v1.32 SMAD4 Zornitza Stark reviewed gene: SMAD4: Rating: RED; Mode of pathogenicity: None; Publications: ; Phenotypes: Pulmonary arterial hypertension MONDO:0015924, SMAD4-related; Mode of inheritance: MONOALLELIC, autosomal or pseudoautosomal, NOT imprinted
Pulmonary Arterial Hypertension v1.18 SMAD4 Bryony Thompson Classified gene: SMAD4 as Red List (low evidence)
Pulmonary Arterial Hypertension v1.18 SMAD4 Bryony Thompson Added comment: Comment on list classification: Disputed classification by ClinGen PH GCEP 21/11/2022
Pulmonary Arterial Hypertension v1.18 SMAD4 Bryony Thompson Gene: smad4 has been classified as Red List (Low Evidence).
Pulmonary Arterial Hypertension v1.0 SMAD9 Elena Savva edited their review of gene: SMAD9: Added comment: Alt gene name SMAD8
gnomAD: pLI = 0. Most frequent NMD-pred PTC has 6 hets in the population, currently a VUS in ClinVar.

PMID: 29844917 - NMD PTC in a 14 year old patient with brain arteriovenous malformation, resulted in reduced phosphorylation of downstream SMAD4. Zebrafish knockdown model showed abnormal cerebral artery-to-vein connection.

PMID: 21920918 - NMD PTC in a patient with heritable pulmonary arterial hypertension. Functional studies on patient cells showed no significant effect in inducing miR-21, miR-27a or miR-100. ID1 (no OMIM) expression was significantly increased.

PMID: 19211612 - NMD PTC in a patient, paternally inherited (also affected with pulmonary arterial hypertension). Functional studies show the protein could not interact with SMAD4, and reduced transcriptional activation activity.; Changed rating: GREEN; Changed mode of inheritance: MONOALLELIC, autosomal or pseudoautosomal, imprinted status unknown
Pulmonary Arterial Hypertension v0.49 SMAD4 Zornitza Stark Marked gene: SMAD4 as ready
Pulmonary Arterial Hypertension v0.49 SMAD4 Zornitza Stark Gene: smad4 has been classified as Amber List (Moderate Evidence).
Pulmonary Arterial Hypertension v0.36 SMAD4 Bryony Thompson Classified gene: SMAD4 as Amber List (moderate evidence)
Pulmonary Arterial Hypertension v0.36 SMAD4 Bryony Thompson Added comment: Comment on list classification: Two reported cases with PAH
Pulmonary Arterial Hypertension v0.36 SMAD4 Bryony Thompson Gene: smad4 has been classified as Amber List (Moderate Evidence).
Pulmonary Arterial Hypertension v0.35 SMAD4 Bryony Thompson gene: SMAD4 was added
gene: SMAD4 was added to Pulmonary Arterial Hypertension. Sources: Literature
Mode of inheritance for gene: SMAD4 was set to MONOALLELIC, autosomal or pseudoautosomal, imprinted status unknown
Publications for gene: SMAD4 were set to 21898662
Phenotypes for gene: SMAD4 were set to Juvenile polyposis/hereditary hemorrhagic telangiectasia syndrome MIM#175050; Pulmonary arterial hypertension
Review for gene: SMAD4 was set to AMBER
Added comment: A missense with reduced in vitro signalling activity and a putative splice site mutation resulting in moderate transcript loss due to compromised splicing efficiency were identified in two PAH cases.
