<div class="spaceAbove">Emery-Dreifuss muscular dystrophy (EDMD) is characterized by the clinical triad of: joint contractures that begin in early childhood; slowly progressive muscle weakness and wasting initially in a humero-peroneal distribution that later extends to the scapular and pelvic girdle muscles; and cardiac involvement that may manifest as palpitations, presyncope and syncope, poor exercise tolerance, and congestive heart failure along with variable cardiac rhythm disturbances. Age of onset, severity, and progression of muscle and cardiac involvement demonstrate both inter- and intrafamilial variability. Clinical variability ranges from early onset with severe presentation in childhood to late onset with slow progression in adulthood. In general, joint contractures appear during the first two decades, followed by muscle weakness and wasting. Cardiac involvement usually occurs after the second decade and respiratory function may be impaired in some individuals.</div>

<div class="spaceAbove">Danon disease is a multisystem condition with predominant involvement of the heart, skeletal muscles, and retina, with overlying cognitive dysfunction. Males are typically more severely affected than females. Males usually present with childhood onset concentric hypertrophic cardiomyopathy that is progressive and often requires heart transplantation. Rarely, hypertrophic cardiomyopathy can evolve to resemble dilated cardiomyopathy. Most affected males also have cardiac conduction abnormalities. Skeletal muscle weakness may lead to delayed acquisition of motor milestones. Learning disability and intellectual disability, most often in the mild range, are common. Additionally, affected males can develop retinopathy with subsequent visual impairment. The clinical features in females are broader and more variable. Females are more likely to have dilated cardiomyopathy, with a smaller proportion requiring heart transplantation compared to affected males. Cardiac conduction abnormalities, skeletal muscle weakness, mild cognitive impairment, and pigmentary retinopathy are variably seen in affected females.</div>

Complicated SPGs are accompanied by additional neurologic symptoms such as cerebellar ataxia, sensory loss, mental retardation, nystagmus, and optic atrophy (summary by Steinmuller et al., 1997).&#13; A locus for spastic paraplegia-16 has been mapped to Xq11.2-q23 (Steinmuller et al., 1997).&#13; For a discussion of genetic heterogeneity of X-linked spastic paraplegia, see 303350.</div>

<div class="spaceAbove">Spastic paraplegia-5A (SPG5A) is an autosomal recessive neurologic disorder with a wide phenotypic spectrum. Some patients have pure spastic paraplegia affecting only gait, whereas others may have a complicated phenotype with additional manifestations, including optic atrophy or cerebellar ataxia (summary by Arnoldi et al., 2012).&#13; The hereditary spastic paraplegias (SPG) are a group of clinically and genetically diverse disorders characterized by progressive, usually severe, lower extremity spasticity; see reviews of Fink et al. (1996) and Fink (1997).

Most affected individuals have onset in the first or second decades of slowly progressive distal motor weakness and atrophy, resulting in gait instability and distal upper limb impairment, as well as distal sensory impairment. More severely affected individuals may have pes cavus and claw hands and become wheelchair-bound, whereas other affected individuals have later onset with a milder disease course. Electrophysiologic studies tend to show median motor nerve conduction velocities (NCV) in the 'intermediate' range, between 25 and 45 m/s (summary by Berciano et al., 2017).&#13; In a review of intermediate CMT, Berciano et al. (2017) noted that advanced axonal degeneration may induce secondary demyelinating changes resulting in decreased NCV and attenuated compound muscle action potential (CMAP) in median nerve conduction studies. They thus suggested that testing the upper arm, axilla to elbow, may provide more accurate assessment of NCV and CMAP and reveal an intermediate phenotype (review by Berciano et al., 2017).&#13; For a discussion of genetic heterogeneity of CMTDI, see 606482.</div>

<div class="spaceAbove">Autosomal recessive limb-girdle muscular dystrophy-28 (LGMDR28) is characterized by progressive muscle weakness affecting the proximal and axial muscles of the upper and lower limbs. The age at onset is highly variable, usually in the first decade, although onset in the fourth decade has also been reported. The disorder can be rapidly progressive or show a slower course. Most patients have limited ambulation or become wheelchair-bound within a few decades, and respiratory insufficiency commonly occurs. Laboratory studies show increased serum creatine kinase and elevated fasting blood glucose levels, although cholesterol is normal. EMG shows a myopathic pattern; muscle biopsy is generally unremarkable, but can show nonspecific myopathic or dystrophic features (Yogev et al., 2023; Morales-Rosado et al., 2023).&#13; For a discussion of genetic heterogeneity of autosomal recessive limb-girdle muscular dystrophy, see LGMDR1 (253600).</div>

<div class="spaceAbove">Autosomal recessive distal hereditary motor neuronopathy-9 (HMNR9) is a slowly progressive peripheral neuropathy characterized by juvenile onset of distal muscle weakness and atrophy, resulting in gait difficulties. Most affected individuals also have upper limb involvement with weakness and atrophy of the hand muscles. Foot deformities are often present. Some patients may have mild sensory abnormalities or pyramidal signs. Electrophysiologic studies are consistent with a length-dependent axonal motor neuropathy (summary by Jacquier et al., 2023).&#13; For a discussion of genetic heterogeneity of autosomal recessive HMN, see HMNR1 (604320).</div>
