| Prepair 1000+ v1.1367 | MUT |
Lauren Thomas changed review comment from: Isolated methylmalonic aciduria is found in patients with mutations in the MUT gene causing partial, mut(-), or complete, mut(0), enzyme deficiency. Variable severity and age of onset: • Infantile completely deficient (mut0) or non-B12-responsive (clbB) is the most common phenotype and presents during infancy. Infants are normal at birth, but develop lethargy, vomiting, and dehydration within the first few months of life. They may also exhibit hepatomegaly, hypotonia, encephalopathy, metabolic acidosis, ketosis and ketonuria, hyperammonemia, and hyperglycemia. • Partially deficient (mut-) or B12-responsive (cblA, cblD, rarely cblB) is an intermediate phenotype that can occur in the first few months or years of life. Symptoms include feeding problems, failure to thrive, hypotonia, and developmental delay. Some have protein aversion and vomiting, and lethargy after protein intake. HGNC approved symbol/name: MMUT * Is the phenotype(s) severe and onset <18yo? Yes Treatments available: cobalamin, N-carbamylglutamate, carnitine, diet, liver transplant Known technical challenges?

| Prepair 1000+ v1.122 | ARV1 | Lilian Downie Added comment: Comment when marking as ready: Developmental and epileptic encephalopathy-38 (DEE38) is an autosomal recessive neurologic and neurodegenerative disorder characterized by the onset of various type of seizures usually between about 4 and 7 months of age. Prior to the onset of seizures, most infants show severely impaired global development, hypotonia with poor head control, and visual inattention with roving eye movements and nystagmus. Seizures are usually refractory to treatment and associated with status epilepticus. Patients have little or no development with inability to walk or speak, spasticity or abnormal movements, and often cortical blindness. There is failure to thrive, and many require tube-feeding. Death in early childhood due to aspiration or intractable epilepsy may occur. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

Sources: Literature Mode of inheritance for gene: BTD was set to BIALLELIC, autosomal or pseudoautosomal Publications for gene: BTD were set to 16435182; 20301497; 32440248 Phenotypes for gene: BTD were set to Biotinidase deficiency (MIM#253260) Review for gene: BTD was set to RED Added comment: Well-established gene disease association. Genotype/phenotype correlations in biotinidase deficiency are not well established, decisions regarding treatment should be based on the results of enzyme activity rather than molecular genetic testing. May be challenging to predict phenotypic outcome in a carrier screening context. Sources: Literature |
