Primary immunodeficiency or monogenic inflammatory bowel disease
Gene: PRF1Comment on list classification: Changed rating of gene from Red to Green. This gene was rated as Green in v2.208 and incorrectly automatically demoted to Red in v2.209. This was due to a defect in the automatic PanelApp uploading tool when a set of publications was added to the panel with the source ‘Other’, and under certain conditions associated to previous sources listed, resulted in the rating of the gene being automatically changed when it should not have been.Created: 14 Oct 2020, 1:41 p.m. | Last Modified: 14 Oct 2020, 1:41 p.m.

Comment on list classification: Changed status from Amber to Green, there are more than 3 unrelated cases to support the phenotype Familial hemophagocytic lymphohistiocytosis-2 (FHL2) caused by homozygous or compound heterozygous mutation in the gene encoding perforin PRF1. Publications include: Goransdotter Ericson et al. (2001) PMID:11179007, where FHL2 was confirmed by genetic analysis reported 7 unrelated families. In PMID:10583959 Stepp et al. (1999) reported 8 unrelated patients with familial hemophagocytic lymphohistiocytosis linked to 10q21-q22, they sequenced the coding region of the PRF1 gene and identified homozygous nonsense mutations in 4 patients and missense mutations in the other 4 patients.Created: 30 Apr 2018, 9:51 a.m.

From OMIM: Familial hemophagocytic lymphohistiocytosis-2 (FHL2) is an autosomal recessive disorder of immune dysregulation with onset in infancy or early childhood. It is characterized clinically by fever, edema, hepatosplenomegaly, and liver dysfunction. Neurologic impairment, seizures, and ataxia are frequent. Laboratory studies show pancytopenia, coagulation abnormalities, hypofibrinogenemia, and hypertriglyceridemia.Created: 30 Apr 2018, 9:41 a.m.
