| Mendeliome v1.1581 | TUBA4A |
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 Mode of inheritance for gene: TNNC2 was set to MONOALLELIC, autosomal or pseudoautosomal, NOT imprinted Publications for gene: TNNC2 were set to 33755597 Phenotypes for gene: TNNC2 were set to Congenital myopathy, MONDO:0019952, TNNC2-related Review for gene: TNNC2 was set to GREEN Added comment: Two families reported: Family 1: 4 individuals, three generations; missense variant p.(Asp34Tyr) Family 2: de novo variant, missense p.(Met79Ile) Physiological studies in myofibers isolated from patients’ biopsies revealed a markedly reduced force response of the sarcomeres to [Ca2+]. This pathomechanism was further confirmed in experiments in which contractile dysfunction was evoked by replacing TnC in myofibers from healthy control subjects with recombinant, mutant TnC. Conversely, the contractile dysfunction of myofibers from patients was repaired by replacing endogenous, mutant TnC with recombinant, wild-type TnC. Borderline Green: sufficient segregation in Fam 1 plus de novo status in Fam 2, plus functional data. Sources: Literature |

MET c.3701A>G p.Y1234C segregated as heterozygous in 11 affected family members and was absent from 12 unaffected family members. Variant is absent from gnomad. Functional studies showed this variant caused failure of phosphorylation and loss of tyrosine kinase activity of MET receptor. A mouse model was also created with this variant, mutated mice were found to be smaller than WT mice and had reduced myofibres. These mouse models also had defective migration of muscle progenitor cells and impaired proliferation of secondary myoblasts. Phenotypes in this family included camptodactyly, absent flexion crease, and limited forearm supination.; to: PMID 30777867: Four-generation Chinese arthrogryposis pedigree with only upper limb involvement.

| Mendeliome v0.7084 | FBN2 |
Zornitza Stark edited their review of gene: FBN2: Added comment: The association between mono-allelic variants in FBN2 and CCA is well established. Recent report of bi-allelic variants, Kloth (2021): biallelic FBN2 variants (PTC/missense) in a teenager with severe CCA, including cardiac defects, mild scoliosis and muscular involvement. Carrier parents both "healthy/unaffected". Phenotype matches mouse K/O. Authors performed a lit review and identified an additional 2 homozygous patients (both missense variants) with - fetal akinesia, brain ischemia and neonatal death - severe muscle weakness with bilateral clubfeet, a pronounced gait disturbance, recurrent patellar dislocations, flexion contractures, camptodactyly, widespread striae and an unusual myofibrillar disorganization, variation in fiber size and atrophic fibers in muscle biopsy. Evidence for association with Macular degeneration, early-onset MIM#616118 is limited. One family reported, plus some rare variants reported in cohort studies. The familial variant p.Glu1144Lys is present in 11 hets in gnomad and has benign in silicos. The second variant reported in the paper, p.Met1247Thr is present in >20 hets.; Changed rating: GREEN; Changed publications: 33571691; Changed phenotypes: Contractural arachnodactyly, congenital MIM#121050, Macular degeneration, early-onset MIM#616118; Changed mode of inheritance: BOTH monoallelic and biallelic, autosomal or pseudoautosomal |
