Medium match SPINAL AND BULBAR MUSCULAR ATROPHY, X-LINKED 1; SMAX1

Kennedy disease is an X-linked recessive form of spinal muscular atrophy. It occurs only in men. Age at onset is usually in the third to fifth decade of life, but earlier involvement has been reported. The disorder is characterized by slowly progressive limb and bulbar muscle weakness with fasciculations, muscle atrophy, and gynecomastia (Harding et al., 1982). The disorder is clinically similar to, but genetically distinct from, classic forms of autosomal spinal muscular atrophy (see, e.g., SMA1; {253300}).

Low match PONTOCEREBELLAR HYPOPLASIA, TYPE 1B; PCH1B

Pontocerebellar hypoplasia type 1B is a severe autosomal recessive neurologic disorder characterized by a combination of cerebellar and spinal motor neuron degeneration beginning at birth. There is diffuse muscle weakness, progressive microcephaly, global developmental delay, and brainstem involvement (summary by Wan et al., 2012). PCH1B can be divided into mild, moderate, and severe subgroups that vary in age at onset, progression, clinical and neuroradiologic severity, and survival (summary by Halevy et al., 2014).For a phenotypic description and a discussion of genetic heterogeneity of PCH, see PCH1A (OMIM ).

Low match CORPUS CALLOSUM AGENESIS-NEURONOPATHY SYNDROME

Corpus callosum agenesis-neuronopathy syndrome is a neurodegenerative disorder characterized by severe progressive sensorimotor neuropathy beginning in infancy with resulting hypotonia, areflexia, amyotrophy and variable degrees of dysgenesis of the corpus callosum. Additional features include mild-to-severe intellectual and developmental delays, and psychiatric manifestations that include paranoid delusions, depression, hallucinations, and "autistic-like" features. Affected individuals are usually wheelchair restricted in the second decade of life and die in the third decade of life. The disease is inherited as an autosomal recessive trait.

Low match AMYOTROPHIC LATERAL SCLEROSIS-PARKINSONISM-DEMENTIA COMPLEX

Amyotrophic lateral sclerosis-parkinsonism/dementia complex of Guam is a neurodegenerative disorder with unusually high incidence among the Chamorro people of Guam. Both ALS and parkinsonism-dementia are chronic, progressive, and uniformly fatal disorders in this population. Both diseases are known to occur in the same kindred, the same sibship, and even the same individual.
