BBS2 is an autosomal recessive ciliopathy characterized by retinal degeneration, polydactyly, renal disease, hypogonadism, obesity, dysmorphic features, and variable degrees of cognitive impairment (Innes et al., 2010). Mutation in the BBS2 gene is the third most frequent cause of BBS, accounting for approximately 8% of cases (Zaghloul and Katsanis, 2009).For a general phenotypic description and a discussion of genetic heterogeneity of Bardet-Biedl syndrome, see BBS1 (OMIM ).

Congenital sideroblastic anemia -B cell immunodeficiency- periodic fever-developmental delay syndrome is a form of constitutional sideroblastic anemia (see this term), characterized by severe microcytic anemia, B-cell lymphopenia , panhypogammaglobulinemia and variable neurodegeneration. The disease presents in infancy with recurrent febrile illnesses, gastrointestinal disturbances, developmental delay, seizures, ataxia and sensorineural deafness. Most patients require regular blood transfusion, iron chelation, and intravenous immunoglobulin (IVIG) replacement. Stem cell transplantation has been reported to be successful.

Low match MUSCULAR DYSTROPHY-DYSTROGLYCANOPATHY (CONGENITAL WITH MENTAL RETARDATION), TYPE B, 1; MDDGB1

Congenital muscular dystrophies resulting from defective glycosylation of alpha-dystroglycan (DAG1 ) are characterized by early onset of muscle weakness, usually before ambulation is achieved; mental retardation and mild brain anomalies are variable (Balci et al., 2005; Godfrey et al., 2007). Congenital muscular dystrophy-dystroglycanopathies with or without mental retardation (type B) represent the intermediate range of the spectrum of dystroglycanopathies. They are less severe than muscular dystrophy-dystroglycanopathy with brain and eye anomalies (type A; see MDDGA1, {236670}), previously designated Walker-Warburg syndrome (WWS) or muscle-eye-brain disease (MEB), and more severe than limb-girdle muscular dystrophy-dystroglycanopathy (type C; see MDDGC1, {609308}). Genetic Heterogeneity of Congenital Muscular Dystrophy-Dystroglycanopathy with or without Mental Retardation (Type B)Congenital muscular dystrophy with mental retardation due to defective glycosylation of DAG1 is genetically heterogeneous.

NEMMLAS is an autosomal recessive multisystemic disorder characterized by delayed psychomotor development, intellectual disability, and abnormal motor function, including hypotonia, dystonia, ataxia, and spasticity. Patient tissues may show deficiencies in one or more of the mitochondrial oxidative phosphorylation (OXPHOS) enzymes, but this is not a constant finding (summary by Wortmann et al., 2017).

Ataxia with vitamin E deficiency (AVED) is a neurodegenerative disease belonging to the inherited cerebellar ataxias. It is mainly characterized by progressive spino-cerebellar ataxia, loss of proprioception, areflexia, and is associated with a marked deficiency in vitamin E.

The neuronal ceroid lipofuscinoses (NCL; CLN) are a clinically and genetically heterogeneous group of neurodegenerative disorders characterized by the intracellular accumulation of autofluorescent lipopigment storage material in different patterns ultrastructurally. The clinical course includes progressive dementia, seizures, and progressive visual failure (Mole et al., 2005).For a discussion of genetic heterogeneity of neuronal ceroid lipofuscinosis, see CLN1 (OMIM ).

Low match PEROXISOME BIOGENESIS DISORDER 9B; PBD9B

While most patients of PBD complementation group 11 manifest rhizomelic chondrodysplasia punctata (RCDP1 ), a few have been reported with unusually mild phenotypes with longer survival, less neurologic involvement, normal or near-normal growth, and absence of rhizomelia (Braverman et al., 2002). In some cases this phenotype was indistinguishable from that of classic Refsum disease (OMIM ) and patients carried this diagnosis.Individuals with PBDs of complementation group 11 (CG11, equivalent to CGR) have mutations in the PEX7 gene. For information on the history of PBD complementation groups, see {214100}.
