Adrenomyeloneuropathy (disorder)	Associated morphology	True	Dystrophy	Inferred relationship	Some	2
A rare autosomal recessive limb-girdle muscular dystrophy characterized by childhood to adult onset of slowly progressive limb girdle muscular weakness, often accompanied by calf hypertrophy, and moderately elevated creatine kinase levels. Patients remain ambulatory but may variably present mild intellectual disability, seizures, migraine, or cardiopulmonary involvement. Occurrence of dilated cardiomyopathy has been reported. Brain MRI typically shows hyperintensity in T2-weighted sequences. Muscle biopsy commonly reveals dystrophic features.	Associated morphology	True	Dystrophy	Inferred relationship	Some	1
A rare autosomal recessive limb-girdle muscular dystrophy characterized by infantile to adolescent onset of a milder form of limb-girdle muscular dystrophy with or without intellectual disability. Patients present variable proximal limb muscular weakness with calf hypertrophy and elevated serum creatine kinase.	Associated morphology	True	Dystrophy	Inferred relationship	Some	1
A rare autosomal dominant limb-girdle muscular dystrophy characterized by adult onset of proximal muscle weakness, pain, and wasting predominantly affecting the proximal leg, lumbar paraspinal, and medial gastrocnemius muscles. Upper limb involvement may also be observed in some cases. Serum creatine kinase is often, but not always, elevated, and muscle biopsy shows non-specific myopathic changes. The severity of the disease is variable, although most patients remain ambulatory.	Associated morphology	True	Dystrophy	Inferred relationship	Some	1
A rare mitochondrial disease characterized by early infantile onset of progressive neurological deterioration with seizures, spasticity, and lack of psychomotor development. Brain imaging shows severe leukodystrophy and abnormalities of neuronal migration. Lactic acidosis is common. The disease is usually fatal in early childhood.

Nail dystrophy caused by chemical	Associated morphology	True	Dystrophy	Inferred relationship	Some	1
A clinically heterogeneous progressive condition with characteristics of a combination of proximal neurogenic muscle weakness, sensory-motor neuropathy, ataxia, and pigmentary retinopathy. NARP syndrome is a maternally inherited syndrome and women can transmit to all their offspring. Clinical severity usually depends on the mutation load.

Cholestanol storage disease	Associated morphology	True	Dystrophy	Inferred relationship	Some	2
A rare genetic neurometabolic disease characterised by microcephaly, short stature, epilepsy, cerebral hypomyelination, severe global developmental delay, and progressive spasticity. Macrocytic anaemia and hyperthermia have also been reported in association. Brain imaging reveals delayed myelination with minimal progression over time, mild cerebellar atrophy and/or thin corpus callosum.	Associated morphology	True	Dystrophy	Inferred relationship	Some	2
A rare genetic neurological disorder with characteristics of hypomyelination of early myelinating structures such as the brainstem, cerebellar white matter, optic radiation, and periventricular white matter, while structures acquiring myelin later are better myelinated. Patients present in infancy with nystagmus, developmental delay, and progressive ataxic-spastic or ataxic syndrome. Cognitive functions are normal or only mildly impaired.	Associated morphology	True	Dystrophy	Inferred relationship	Some	2
An astrogliopathy and a form of Alexander disease (AxD) characterized by ataxia, bulbar symptoms, spastic paraparesis, palatal myoclonus, and autonomic symptoms.	Associated morphology	True	Dystrophy	Inferred relationship	Some	2
Total peripapillary choroidal dystrophy	Associated morphology	True	Dystrophy	Inferred relationship	Some	1

A form of congenital muscular dystrophy characterized by congenital weakness, hypotonia, proximal joint contractures, marked hyperlaxity of the distal joints, attainment of independent ambulation which is subsequently lost and uniform respiratory insufficiency during the teenage years. Intermediate COL6-RD is caused by heterozygous or biallelic pathogenic variants (PVs) in the genes coding for the alpha chains of the extracellular matrix protein collagen VI (COL6A1, COL6A2, and COL6A3).	Associated morphology	True	Dystrophy	Inferred relationship	Some	1
A rare primary bone dysplasia characterised by severe spondyloepiphyseal dysplasia, sensorineural hearing loss, intellectual disability and Leber congenital amaurosis. Brain anomalies (including delayed myelinisation, white matter hyperintensity, hypomyelinating leucoencephalopathy, cerebral and cerebellar hypoplasia/atrophy), hypotonia, ataxia, dysmorphic facial features (including deep nasal bridge and large mouth) and irregular dentition were also reported.	Associated morphology	True	Dystrophy	Inferred relationship	Some	2
Trachyonychia	Associated morphology	True	Dystrophy	Inferred relationship	Some	1
A rare, isolated nail anomaly characterised by brittle, thin, rough, opaque appearing nails with excessive longitudinal ridging. In a less severe form, the nails retain their luster and present with superficial ridging and multiple small geometric pits. In both varieties, superficial scaling of the nail plate and hyperkeratosis of the cuticles, as well as koilonychia and onychoschizia are observed. Any number of nails may be affected, and fingernails are more often affected than toenails. Spontaneous improvement of the condition may occur.
