DEDSM is a neurodevelopmental disorder characterized by global developmental delay, variable intellectual disability, and early-onset seizures with a myoclonic component. Most patients have delayed motor development and show abnormal movements, including ataxia, dystonia, and tremor (summary by Hamdan et al., 2017).

Medium match 6-PYRUVOYL-TETRAHYDROPTERIN SYNTHASE DEFICIENCY

6-pyruvoyl-tetrahydropterin synthase (PTPS) deficiency is one of the causes of malignant hyperphenylalaninemia due to tetrahydrobiopterin deficiency. Not only does tetrahydrobiopterin deficiency cause hyperphenylalaninemia, it is also responsible for defective neurotransmission of monoamines because of malfunctioning tyrosine and tryptophan hydroxylases, both tetrahydrobiopterin-dependent hydroxylases.

Medium match PARKINSON DISEASE, LATE-ONSET; PD

Parkinson disease was first described by James Parkinson in 1817. It is the second most common neurodegenerative disorder after Alzheimer disease (AD ), affecting approximately 1% of the population over age 50 (Polymeropoulos et al., 1996). ReviewsWarner and Schapira (2003) reviewed the genetic and environmental causes of Parkinson disease. Feany (2004) reviewed the genetics of Parkinson disease and provided a speculative model of interactions among proteins implicated in PD. Lees et al. (2009) provided a review of Parkinson disease, with emphasis on diagnosis, neuropathology, and treatment. Genetic Heterogeneity of Parkinson DiseaseSeveral loci for autosomal dominant Parkinson disease have been identified, including PARK1 (OMIM ) and PARK4, caused by mutation in or triplication of the alpha-synuclein gene (SNCA ), respectively, on 4q22; PARK5 (OMIM ), caused by mutation in the UCHL1 gene on 4p13; PARK8 (OMIM ), caused by mutation in the LRRK2 gene (OMIM ) on 12q12; PARK11 (OMIM ), caused by mutation in the GIGYF2 gene (OMIM ) on 2q37; PARK13 (OMIM ), caused by mutation in the HTRA2 gene (OMIM ) on 2p13; PARK17 (OMIM ), caused by mutation in the VPS35 gene (OMIM ) on 16q11; and PARK18 (OMIM ), caused by mutation in the EIF4G1 gene (OMIM ) on 3q27.Several loci for autosomal recessive early-onset Parkinson disease have been identified: PARK2 (OMIM ), caused by mutation in the gene encoding parkin (PARK2 ) on 6q26; PARK6 (OMIM ), caused by mutation in the PINK1 gene (OMIM ) on 1p36; PARK7 (OMIM ), caused by mutation in the DJ1 gene (PARK7 ) on 1p36; PARK14 (OMIM ), caused by mutation in the PLA2G6 gene (OMIM ) on 22q13; PARK15 (OMIM ), caused by mutation in the FBXO7 gene (OMIM ) on 22q12-q13; PARK19A (OMIM ) and PARK19B (see {615528}), caused by mutation in the DNAJC6 gene (OMIM ) on 1p32; and PARK20 (OMIM ), caused by mutation in the SYNJ1 gene (OMIM ) on 21q22.PARK3 (OMIM ) has been mapped to chromosome 2p13; PARK10 (OMIM ) has been mapped to chromosome 1p34-p32; PARK16 (OMIM ) has been mapped to chromosome 1q32. See also PARK21 (OMIM ). A locus on the X chromosome has been identified (PARK12 ). There is also evidence that mitochondrial mutations may cause or contribute to Parkinson disease (see {556500}). Susceptibility to the development of the more common late-onset form of Parkinson disease has been associated with polymorphisms or mutations in several genes, including GBA (OMIM ), MAPT (OMIM ), MC1R (OMIM ), ADH1C (OMIM ), and genes at the HLA locus (see, e.g., HLA-DRA, {142860}). Each of these risk factors independently may have a modest effect on disease development, but together may have a substantial cumulative effect (Hamza et al., 2010).Susceptibility to PD may also be conferred by expanded trinucleotide repeats in several genes causing other neurologic disorders usually characterized by spinocerebellar ataxia (SCA), including the ATXN2 (OMIM ), ATXN3 (OMIM ), TBP (OMIM ), and ATXN8OS (OMIM ) genes.
