Low match PEROXISOME BIOGENESIS DISORDER 14B; PEX14B

PBD14B is an autosomal recessive peroxisome biogenesis disorder characterized clinically by mild intellectual disability, congenital cataracts, progressive hearing loss, and polyneuropathy (Ebberink et al., 2012), all of which had been observed in patients with mild peroxisomal biogenesis disorders (e.g., Kelley et al., 1986; Poll-The et al., 1987). Additionally, recurrent migraine-like episodes following mental stress or physical exertion, not a common feature in peroxisome disorders, was reported.Thoms and Gartner (2012) classified the disorder described by Ebberink et al. (2012) in their patient as a mild 'Zellweger syndrome (OMIM ) spectrum' (ZSS) disorder. See PBD1B (OMIM ) for a phenotypic description and discussion of genetic heterogeneity of less severe phenotypes on the Zellweger syndrome spectrum. See PBD9B (OMIM ) for another atypical peroxisome biogenesis disorder.

Low match AUTOSOMAL RECESSIVE SPASTIC PARAPLEGIA TYPE 5A

Autosomal recessive spastic paraplegia type 5A is a form of hereditary spastic paraplegia characterized by either a pure phenotype of slowly progressive spastic paraplegia of the lower extremities with bladder dysfunction and pes cavus or a complex presentation with additional manifestations including cerebellar signs, nystagmus, distal or generalized muscle atrophy and cognitive impairment. Age of onset is highly variable, ranging from early childhood to adulthood. White matter hyperintensity and cerebellar and spinal cord atrophy may be noted, on brain magnetic resonance imaging, in some patients.

Low match AUTOSOMAL RECESSIVE SPASTIC PARAPLEGIA TYPE 46

Autosomal recessive spastic paraplegia type 46 (SPG46) is a rare, complex type of hereditary spastic paraplegia characterized by an onset, in infancy or childhood, of the typical signs of spastic paraplegia (i.e. spastic gait and weakness of the lower limbs) associated with a variety of additional manifestations including upper limb spasticity and weakness, pseudobulbar dysarthria, bladder dysfunction, cerebellar ataxia, cataracts, and cognitive impairment that can progress to dementia. Brain imaging may show thinning of the corpus callosum and mild atrophy of the cerebrum and cerebellum. SPG46 is due to mutations in the GBA2 gene (9p13.2) encoding non-lysosomal glucosylceramidase.

Autosomal dominant spastic paraplegia-9A is a neurologic disorder characterized by onset of slowly progressive spasticity mainly affecting the lower limbs. The age at onset usually ranges from adolescence to adulthood, and patients have gait difficulties, motor neuropathy, and dysarthria. Additional variable features include cerebellar signs, cataract, pes cavus, and urinary urgency (summary by Coutelier et al., 2015).For a general phenotypic description and a discussion of genetic heterogeneity of autosomal dominant spastic paraplegia, see SPG3A (OMIM ).

Low match METHYLMALONIC ACIDURIA AND HOMOCYSTINURIA, CBLC TYPE; MAHCC

Combined methylmalonic aciduria (MMA) and homocystinuria is a genetically heterogeneous disorder of cobalamin (cbl; vitamin B12) metabolism. The defect causes decreased levels of the coenzymes adenosylcobalamin (AdoCbl) and methylcobalamin (MeCbl), which results in decreased activity of the respective enzymes methylmalonyl-CoA mutase (MUT ) and methyltetrahydrofolate:homocysteine methyltransferase, also known as methionine synthase (MTR ). Different forms of the disorder have been classified according to complementation groups of cells in vitro: cblC, cblD (OMIM ), cblF (OMIM ), and cblJ (OMIM ).Isolated methylmalonic acidurias have also been classified by complementation groups: MMA 'mut' (OMIM ) is caused by mutation in the MUT gene on chromosome 6p21; MMA cblA (OMIM ) is caused by mutation in the MMAA gene (OMIM ) on 4q31; and MMA cblB (OMIM ) is caused by mutation in the MMAB gene (OMIM ) on 12q24.Methylmalonic aciduria and homocystinuria, cblC type, is the most common inborn error of vitamin B12 (cobalamin) metabolism, with about 250 known cases (Lerner-Ellis et al., 2006). Affected individuals may have developmental, hematologic, neurologic, metabolic, ophthalmologic, and dermatologic clinical findings. Although considered a disease of infancy or childhood, some individuals develop symptoms in adulthood (Rosenblatt et al., 1997).
