Gene: CCBE1Comment when marking as ready: Rated as green, and mode of inheritance complete.Created: 19 Dec 2016, 1:50 p.m.
Comment on list classification: Updated rating from Grey to Green: 2 Green reviews (including one from gene submitter). Confirmed DD gene for HKLLS1 (OMIM:235510). >3 unrelated cases of CBBE1 mutations causing HKLLS1 in OMIM, and sufficient link between HKLLS1 and Fetal hydrops in literature and Reviewer experience.Created: 19 Dec 2016, 1:50 p.m.
PMID:12794699 (Bellini et al., 2003) report a female infant with congenital lymphedema, facial anomalies, intestinal lymphangiectasia consistent with a diagnosis of Hennekam syndrome. At birth the patient presented with severe respiratory distress due to nonimmune hydrops fetalis, a congenital chylothorax (CC), and pulmonary lymphangiectasia. Hydrops fetalis may be present in newborns with the Hennekam syndrome.Created: 19 Dec 2016, 11:45 a.m.
CCBE1 is a confirmed DD gene for HKLLS1 (Hennekam lymphangiectasia-lymphedema syndrome 1, OMIM:235510), which can present with fetal hydrops. OMIM reports >3 unrelated cases of CBBE1 mutations causing HKLLS1.Created: 15 Dec 2016, 1:54 p.m.
PMID:24086631 (Shah et al., 2013) report a homozygous CCBE1 missense mutation c.398 T>C (L133P) in two siblings from consanguineous parents of Mexican ancestry, one manifesting lymphedema-cholestasis syndrome (LCS), and the other, fetal hydrops.Created: 15 Dec 2016, 1:47 p.m.

Phenotypes for gene: CCBE1 were changed from Hennekam lymphangiectasia-lymphedema syndrome 1, 235510; generalised lymphatic dysplasia; fetal hydrops to Hennekam lymphangiectasia-lymphedema syndrome 1, OMIM:235510; generalised lymphatic dysplasia; fetal hydrops
21 December 2016. External reviews were assessed, and panel was revised according to expert review, internal discussion and additional curation. Following internal discussion, all genes from the V1.14 'RASopathies' panel were added as green EXCLUDING NF1 and SPRED1- a cautious approach was taken because Fetal hydrops is a fetal panel. All relevant genes from the 'Mucopolysaccharideosis, Gaucher, Fabry' V1.0 panel (lysosomal storage disorders) were also added to the Fetal hydrops panel as green together with genes from the literature where there is a reasonable link between the corresponding lysosomal storage disorder (LSD) and Fetal hydrops. All PEX genes from the V1.2 'Peroxisomal disorders' panel were added as green based on a link between peroxisomal biogenesis disorders and Fetal hydrops.
This gene has been classified as Green List (High Evidence).
