Comment on list classification: Updated rating from Red to Green based on Green review by an expert. 2 unrelated cases plus a mouse model.
Created: 7 Feb 2017, 3:22 p.m.
Gautam et al., 1996/PMID:8653788 (amongst others) provide a mouse model where knockout mice deficient for agrin showed grossly defective neuromuscular differentiation. See also PMID:21890498.
Created: 31 Jan 2017, 4:20 p.m.
In a 39-year-old man with congenital myasthenic syndrome-8 (OMIM:615120), Maselli et al. (2012, PMID:22205389) identified compound heterozygosity for 2 mutations in the AGRN gene: V1727F and Q353X.
Created: 31 Jan 2017, 4:16 p.m.
In a sister and brother with congenital myasthenic syndrome-8 (OMIM:615120), Huze et al. (2009, PMID:19631309) identified a homozygous 5125G-C transversion in AGRN, resulting in a G1709R substitution.
Created: 31 Jan 2017, 4:15 p.m.
Comment on mode of inheritance: Mode of inheritance confirmed by OMIM.
