Comment on mode of inheritance: Updated MOI from hemizygous biallelic to hemizygous monoallelic, after discussion with Helen Brittain. This will ensure a female proband with incomplete X skewing and manifestations can be picked up, in addition to a biallelic case.Created: 29 May 2017, 9:38 a.m.

Comment when marking as ready: Established causation. Hydrocephalus is a major feature of this cause of multiple congenital anomalies. Therefore an appropriate phenotype.Created: 29 Mar 2017, 1:34 p.m.
From OMIM; "Patients with FANCB mutations often present with multiple additional congenital anomalies, including the constellation of features designated VACTERL-H, for vertebral defects, anal atresia, tracheoesophageal fistula, esophageal atresia, radial or renal dysplasia, and hydrocephalus."
"Ventriculomegaly, absent thumbs and radii, or hypoplastic thumbs, and abnormal chromosome breakage are cardinal features."
This is an x-linked form of Fanconi anaemia, but in view of the severity of the congenital anomalies, of which hydrocephalus is a key feature, infants may not survive to the stage where anaemia develops. Therefore it is detected by the presence of major congenital anomalies and as hydrocephalus is one, this seems appropriate for inclusion. Sufficient cases reported for causation.Created: 29 Mar 2017, 1:19 p.m.
