Limb-Girdle Muscular Dystrophy and Distal Myopathy
Gene: UNC45B
Onset is within the first decade of life typically indicated by slow progression of proximal muscle weakness.
PMID: 33217308; 31852522
11 individuals from 9 unrelated families with symptoms of progressive proximal muscle weakness.
PMID: 31852522
Muscle biopsy was conducted on one individual which showed myopathic changes with core-like structures

Comment when marking as ready: 10 individuals from 8 families reported with biallelic variants clinically manifesting with childhood-onset, progressive proximal and axial muscle weakness and various degrees of respiratory insufficiency. 4 missense variants and a +5 splice variant reported, p.Arg754Gln is recurrent. Functional studies support pathogenicity.Created: 7 Dec 2020, 4:56 a.m. | Last Modified: 7 Dec 2020, 4:56 a.m.
