Mendeliome v1.1860 SERPINA11 Ain Roesley Marked gene: SERPINA11 as ready
Mendeliome v1.1860 SERPINA11 Ain Roesley Gene: serpina11 has been classified as Red List (Low Evidence).
Mendeliome v1.1860 SERPINA11 Ain Roesley Phenotypes for gene: SERPINA11 were changed from to pericardial effusion; pleural effusion
Mendeliome v1.1859 SERPINA11 Ain Roesley edited their review of gene: SERPINA11: Changed phenotypes: pericardial effusion, pleural effusion
Mendeliome v1.1859 SERPINA11 Ain Roesley gene: SERPINA11 was added
gene: SERPINA11 was added to Mendeliome. Sources: Literature
Mode of inheritance for gene: SERPINA11 was set to BIALLELIC, autosomal or pseudoautosomal
Publications for gene: SERPINA11 were set to 38831697
Review for gene: SERPINA11 was set to RED
gene: SERPINA11 was marked as current diagnostic
Added comment: 1 family with 2 fetuses.

1st fetus presented with isolated pericardial effusion and a TOP was opted.
post mortem:
mild subcutaneous edema with subtle facial dysmorphic features
small gelatinous glistening cyst on the right pericardium. Bilateral pleural effusion and multiple similar cysts were noted on the lung surfaces

2nd fetus also presented with pleural and pericardial effusion and a TOP was opted
post mortem findings were similar to fetus#1

homozygous nonsense variant in SERPINA11 was found p.(Tyr224*)

Immunofluorescence of lung sections from fetus#1 and a gestation-matched fetus as a control demonstrated undetectable levels of SERPINA11 in the bronchiolar epithelium

Mendeliome v0.12224 SERPINA1 Samantha Ayres changed review comment from: Well established gene-disease relationship

Rated as C by babyseq due to low penetrance in childhood. Can cause hepatic dysfunction in infancy. Identification would prevent further investigation and potentially lead to optimising respiratory health due to adult onset respiratory involvement.; to: Well established gene-disease relationship

Rated as C by babyseq due to low penetrance in childhood. Can cause hepatic dysfunction in infancy. Identification would prevent further investigation and potentially lead to optimising respiratory health due to adult onset respiratory involvement.

MUTATIONAL & CLINICAL SPECTRUM
ZZ genotype: 2% have severe, neonatal/early-onset liver disease (potentially fatal/requiring liver transplantation), up to 6% have childhood onset liver disease. Also associated with adult-onset lung disease particularly emphysema (50%+ penetrance) - smoking is an important risk factor (close to 100% penetrance).

TREATMENT
There is no specific treatment for liver disease beyond transplant. There is treatment (AAT augmentation therapy) available to delay progression of lung disease phenotype.
