An oculopharyngodistal myopathy that is characterized by progressive ptosis, ophthalmoparesis, facial and masseter weakness, and muscle weakness of the distal limbs and that has_material_basis_in heterozygous trinucleotide repeat expansion (CGG) in the 5-prime untranslated region (UTR) of the RILPL1 gene on chromosome 12q24.
- neuronal intranuclear inclusion disease [DOID:0081294]
A neurodegenerative disease that is characterized by a wide range of clinical manifestations, including pyramidal and extrapyramidal symptoms, cerebellar ataxia, cognitive decline and dementia, peripheral neuropathy, and autonomic dysfunction, and that has_material_basis_in heterozygous repeat expansion (CGG) in the 5-prime untranslated region of the NOTCH2NLC gene on chromosome 1q21.
- oculopharyngodistal myopathy 3 [DOID:0081299]
An oculopharyngodistal myopathy that is characterized by progressive muscle weakness with ocular, facial, pharyngeal, and distal limb involvement, resulting in dysarthria and gait difficulties and that has_material_basis_in heterozygous trinucleotide repeat expansion (CGG) in the 5-prime untranslated region (UTR) of the NOTCH2NLC gene on chromosome 1q21.
- oculopharyngodistal myopathy 1 [DOID:0081297]
An oculopharyngodistal myopathy that is characterized by adult-onset ptosis, external ophthalmoplegia, facial muscle weakness, distal limb muscle weakness and atrophy, and pharyngeal involvement, resulting in dysphagia and dysarthria, and that has_material_basis_in heterozygous trinucleotide repeat expansion (CGG) in the 5-prime untranslated region of the LRP12 gene on chromosome 8q22.
- X-linked intellectual developmental disorder 109 [DOID:0080984]
A syndromic X-linked intellectual disability characterized by mildly to moderately impaired intellectual development associated with learning difficulties, communication deficits, attention problems, hyperactivity, and autistic behavior and that has_material_basis_in disruption of the FMR2 gene (AFF2), either by expansion of a CCG repeat in the 5-prime untranslated region or by deletion.
- oculopharyngodistal myopathy 2 [DOID:0081298]
An oculopharyngodistal myopathy that is characterized by onset of distal muscle weakness, mainly of the lower limbs, and/or ophthalmoplegia in the second or third decades of life, and that has_material_basis_in heterozygous trinucleotide repeat expansion (GGC(n)) in the 5-prime untranslated region (UTR) of the GIPC1 gene on chromosome 19p13.
- amyotrophic lateral sclerosis type 28 [DOID:0081382]
An amyotrophic lateral sclerosis that is characterized by adult onset of slowly progressive limb muscle weakness and atrophy resulting in gait difficulties, loss of ambulation, and distal upper limb weakness and that has_material_basis_in a heterozygous trinucleotide repeat expansion (CGG) in the 5-prime untranslated region of the LRP12 gene on chromosome 8q22.
- Peroxisome biogenesis disorder 4B [DOID:0081433]
A peroxisomal biogenesis disorder that is characterized by the overlapping phenotypes of neonatal adrenoleukodystrophy and infantile Refsum disease and that has_material_basis_in homozygous or compound heterozygous mutation in the PEX6 gene on chromosome 6p21.1, or overexpression of a heterozygous mutation in PEX6 due to allelic expression imbalance resulting from a polymorphism on the mutant allele in the PEX6 3-prime UTR.
