Mode of inheritance
MONOALLELIC, autosomal or pseudoautosomal, NOT imprinted

Agenesis of the corpus callosum


Arianna Tucci (Genomics England Curator)

Comment when marking as ready: Marked as amber as out of the three reported families, only two have loss of function mutations and ID. The other proband carries a missense mutation and does not have ID (28250456)

Ellen McDonagh (Genomics England Curator)

I don't know

Currently amber perhaps should be green, as 3 families are reported in PMID: 28250456.

Mode of inheritance
BIALLELIC, autosomal or pseudoautosomal

Midline-bridging neuronal commissure disruption, horizontal gaze palsy, scoliosis, and intellectual disability


Sarah Leigh (Genomics England Curator)

I don't know

Associated with phenotype in OMIM and as a probable G2P. At least 2 homozygous truncating deletion variants reported in two unrelated cases (7682bp and 7bp).

12 Mar 2018, Gel status: 2

Panel promoted to version 2.0

Ellen McDonagh (Genomics England Curator)

12.03.2018: Due to major updates completed (Phase 1, 2 and 3), this panel was promoted to Version 2 in order to reflect the major updates since November 2017 which have resulted in reviews for 836 genes added by Genomics England Curators and the Clinical Team, 130 new Green genes added to the interpretation pipeline (from 751 to 881 Green genes), and the gene total has increased from 1879 to 1927.
