Rolandic epilepsy (RE) is a focal childhood epilepsy characterized by seizures consisting of unilateral facial sensory-motor symptoms, with electroencephalogram (EEG) showing sharp biphasic waves over the rolandic region. It is an age-related epilepsy, with excellent outcome.

Different forms of isolated methylmalonic aciduria have been classified according to complementation groups of cells in vitro. Patients with defects in the synthesis of AdoCbl are usually responsive to vitamin B12 therapy and are classified as 'cbl' type: these include cblA and cblB (OMIM ), which is caused by mutation in the MMAB gene (OMIM ) on 12q24. See also cblH (OMIM ), which may be a subset of cblA. The 'mut' form of MMA (OMIM ) is caused by mutation in the MUT gene on chromosome 6p. In general, the mut form of MMA is unresponsive to vitamin B12 therapy.Combined methylmalonic aciduria and homocystinuria may be seen in complementation groups cblC (OMIM ), cblD (OMIM ), cblF (OMIM ), and cblJ (OMIM ).
VITAMIN B12-RESPONSIVE METHYLMALONIC ACIDEMIA TYPE CBLA Is also known as methylmalonic aciduria, vitamin b12-responsive, due to defect in synthesis of adenosylcobalamin, cbla type|vitamin b12-responsive methylmalonic aciduria type cbla|methylmalonic acidemia, cbla type

Manifestations may include hemolytic uremic syndrome, macrocytosis, epilepsy, hearing loss, retinopathy, mild mental retardation, lymphopenia involving all subsets, and low T-cell receptor excision circles. Folinic acid supplementation is an effective treatment (summary by Ramakrishnan et al., 2016).
COMBINED IMMUNODEFICIENCY AND MEGALOBLASTIC ANEMIA WITH OR WITHOUT HYPERHOMOCYSTEINEMIA; CIMAH Is also known as methylenetetrahydrofolate dehydrogenase 1 deficiency

Glutathione synthetase deficiency, or 5-oxoprolinuria, is an autosomal recessive disorder characterized, in its severe form, by massive urinary excretion of 5-oxoproline, metabolic acidosis, hemolytic anemia, and central nervous system damage. The metabolic defect results in decreased levels of cellular glutathione, which overstimulates the synthesis of gamma-glutamylcysteine and its subsequent conversion to 5-oxoproline (Larsson and Anderson, 2001).

The disorder shows marked phenotypic variability: some patients have a severe multisystem disorder from infancy, including cardiomyopathy and respiratory insufficiency resulting in early death, whereas others present in the second or third decade of life with sideroblastic anemia and mild muscle weakness (summary by Riley et al., 2013).For a discussion of genetic heterogeneity of MLASA, see MLASA1 (OMIM ).
