Medium match LOWER MOTOR NEURON SYNDROME WITH LATE-ADULT ONSET

The Jokela type of spinal muscular atrophy (SMAJ) is an autosomal dominant lower motor neuron disorder characterized by adult-onset of muscle cramps and fasciculations affecting the proximal and distal muscles of the upper and lower limbs. The disorder is slowly progressive, resulting in weakness and mild muscle atrophy later in life (summary by Jokela et al., 2011).

Spinocerebellar ataxia type 23 (SCA23) is a very rare subtype of type I autosomal dominant cerebellar ataxia (ADCA type I; see this term). It is characterized by gait ataxia, dysarthria, slowed saccades, ocular dysmetria, Babinski sign and hyperreflexia.

Charcot-Marie-Tooth disease type 4F (CMT4F) is a severe, demyelinating subtype of Charcot-Marie-Tooth disease type 4 characterized by the childhood onset of a slowly-progressing typical CMT phenotype (i.e. distal muscle weakness and atrophy, as well as pes cavus) that presents severe sensory loss (frequently with sensory ataxia), moderately to severely reduced motor nerve conduction velocities and almost invariable absence of sensory nerve action potentials, and delayed motor milestones.

Medium match CHARCOT-MARIE-TOOTH DISEASE TYPE 2P

Charcot-Marie-Tooth disease type 2P is a rare, genetic, axonal hereditary motor and sensory neuropathy disorder characterized by adulthood-onset of slowly progressive, occasionally asymmetrical, distal muscle weakness and atrophy (predominantly in the lower limbs), pan-modal sensory loss, muscle cramping in extremities and/or trunk, pes cavus and absent or reduced deep tendon reflexes. Gait anomalies and variable autonomic disturbances, such as erectile dysfunction and urinary urgency, may be associated.

Medium match SPASTIC ATAXIA 1, AUTOSOMAL DOMINANT; SPAX1

Hereditary spastic ataxia comprises a heterogeneous group of progressive neurodegenerative disorders characterized by lower-limb spasticity and generalized ataxia with dysarthria, impaired ocular movements, and gait disturbance. Spastic ataxia-1 (SPAX1) is an autosomal dominant form of the disorder with linkage to chromosome 12p13 (summary by Meijer et al., 2002). Genetic Heterogeneity of Spastic AtaxiaSee also SPAX2 (OMIM ), caused by mutation in the KIF1C gene (OMIM ) on chromosome 17p13; SPAX3 (OMIM ), caused by rearrangements of the MARS2 gene (OMIM ) on chromosome 2q33; SPAX4 (OMIM ), caused by mutation in the MTPAP gene (OMIM ) on chromosome 10p11; SPAX5 (OMIM ), caused by mutation in the AFG3L2 gene (OMIM ) on chromosome 18p11; SPAX6 (OMIM ), caused by mutation in the SACS gene (OMIM ) on chromosome 13q12; SPAX7 (OMIM ); and SPAX8 (OMIM ), caused by mutation in the NKX6-2 gene (OMIM ) on chromosome 8q21.
