Medium 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}.

Medium match OPTIC ATROPHY-PERIPHERAL NEUROPATHY-DEVELOPMENTAL DELAY SYNDROME

Harel-Yoon syndrome is a syndromic neurodevelopmental disorder characterized by delayed psychomotor development, intellectual disability, truncal hypotonia, spasticity, and peripheral neuropathy. Other more variable features such as optic atrophy may also occur. Laboratory studies in some patients show evidence of mitochondrial dysfunction (summary by Harel et al., 2016).

Medium match AUTOSOMAL RECESSIVE LIMB-GIRDLE MUSCULAR DYSTROPHY TYPE 2S

Autosomal recessive limb-girdle muscular dystrophy type 2S (LGMD2S) is a form of limb-girdle muscular dystrophy characterized by childhood-onset of progressive proximal muscle weakness (leading to reduced ambulation) with myalgia and fatigue, in addition to infantile hyperkinetic movements, truncal ataxia, and intellectual disability. Additional manifestations include scoliosis, hip dysplasia, and less commonly, ocular features (e.g. myopia, cataract) and seizures.
