Sarah Pantaleo gene: TUBA4A was added gene: TUBA4A was added to Mendeliome. Sources: Literature Mode of inheritance for gene: TUBA4A was set to MONOALLELIC, autosomal or pseudoautosomal, NOT imprinted Publications for gene: TUBA4A were set to PMID: 38413182 Phenotypes for gene: TUBA4A were set to Congenital myopathy MONDO:0019952 Review for gene: TUBA4A was set to AMBER Added comment: One novel TUBA4A variant in two unrelated Chinese patients with sporadic congenital myopathy. Identified candidate genes using laser capture micro dissection, proteomics, WES, clinical data, myopathological changes, electrophysiological exams and thigh muscle MRIs. The variant is de novo in both patients, c.679C>T, p.(Leu227Phe). The prominent myopathological changes in both patients were muscle fibres with focal myofibrillar disorganisation and rimmed vacuoles. Immunofluorescence showed ubiqution-positive TUBA4A protein aggregates in the muscle fibres with rimmed vacuoles. Overexpression of Leu227Phe resulted in cytoplasmic aggregates which colocalised with ubiquitin in cellular model. Patient 1 is 14yo and had delayed motor development milestones since infancy. Myopathic face, high-arched palate, waddling gait, winged scapula and muscle weakness in four limbs with lower extremities and proximal muscle more severely affected. Follow up at 14yo showed slight improvement in motor function compared with 3yo. Patient 2 is 6yo and presented with motor retardation since birth. At 3yo, presented with mild ptosis and ophthalmoparesis, high-arched palate and muscle weakness involving both proximal and distal in all limbs. No likely pathogenic variants in 116 other protein-encoding genes. Variants confirmed by Sanger sequencing and absent from gnomAD. ACMG predicts likely pathogenic classification. Sources: Literature |
