pontocerebellar hypoplasia type 1

A pontocerebellar hypoplasia characterized by spinal cord anterior horn cell degeneration combined with pontocerebellar hypoplasia.

Van Maldergem syndrome 1

A Van Maldergem syndrome that has_material_basis_in homozygous mutation in the DCHS1 gene on chromosome 11p15.

Van Maldergem syndrome 2

A Van Malergem syndrome that has_material_basis_in homozygous or compound heterozygous mutation in the FAT4 gene on chromosome 4q28.

vulvar trichoepithelioma

A vulvar benign neoplasm that derives_from epithelial-mesenchymal origin cells. It is characterized by branching nests of basaloid cells, horn cysts, and abortive hair papillae. The tumors represent benign hamartomas of the pilosebaceous apparatus.

X-linked spinal muscular atrophy 2

A spinal muscular atrophy characterized by neonatal onset of severe hypotonia, areflexia, and multiple congenital contractures associated with loss of anterior horn cells and infantile death that has_material_basis_in hemizygous mutation in the UBA1 gene on chromosome Xp11.3.

autosomal dominant distal hereditary motor neuronopathy

A spinal muscular atrophy that is characterized by progressive distal motor weakness and muscular atrophy of the peripheral nervous system without sensory impairment, that is caused by anterior horn cell degeneration, and that has_material_basis_in autosomal dominant inheritance.

anterior horn cell disease

A motor neuron disease that is characterized by lower motor neuron signs of wasting, weakness, and loss of reflexes and that is located in the anterior horn of the spinal cord that contains the motor neurons responsible for body muscles.

Brown-Vialetto-Van Laere syndrome 1

A Brown-Vialetto-Van Laere syndrome that is characterized by progressive bulbar palsy with sensorineural deafness that has_material_basis_in homozygous or compound heterozygous mutation in the C20ORF54 gene (SLC52A3) on chromosome 20p13.

autosomal dominant distal hereditary motor neuronopathy 1

An autosomal dominant distal hereditary motor neuronopathy that is characterized by progressive distal motor weakness and muscular atrophy of the peripheral nervous system without sensory impairment, that is caused by anterior horn cell degeneration and that has_material_basis_in heterozygous 1.35-Mb DNA insertion on chromosome 7q34-q36.2. This structural variant (SV) results in the production of a novel gene-intergenic fusion transcript, UBE3C-IF.

Brown-Vialetto-Van Laere syndrome 2

A Brown-Vialetto-Van Laere syndrome that is characterized by early childhood onset of sensorineural deafness, bulbar dysfunction, and severe diffuse muscle weakness and wasting of the upper and lower limbs and axial muscles, resulting in respiratory insufficiency and that has_material_basis_in homozygous or compound heterozygous mutation in the SLC52A2 gene on chromosome 8q24.
