Charcot-Marie-Tooth Disease
- Distal Hereditary Motor Neuropathy
Inherited neuropathies that mainly affect motor nerves, causing weakness and wasting of the hands and feet, including SORD-related neuropathy.
- 2 GenCC submitters rate it definitive or strong
Hereditary Spastic Paraplegia
- Hereditary Spastic Paraplegia 12Autosomal dominant
Autosomal dominant spastic paraplegia type 12 is a pure form of hereditary spastic paraplegia characterized by a childhood- to adulthood-onset of slowly progressive lower limb spasticity and hyperreflexia of lower extremities, extensor plantar reflexes, distal sensory impairment, variable urinary dysfunction and pes cavus.
- 2 GenCC submitters rate it definitive or strong
- Hereditary Spastic Paraplegia (All Types)
One of 66 genes linked to it
Umbrella term covering all hereditary spastic paraplegias, including SPG4 (SPAST), the most common dominant form, and SPG5A, SPG6, SPG10, SPG18, SPG30 and SPG31.
- 2 GenCC submitters rate it definitive or strong
Inheritance
- Autosomal dominant
- One changed copy, from either parent, is enough. A parent who has one passes it on to each child with a one-in-two chance.

- Direction of transcription
- Known disease-causing sites
- Stretches short reads find hard
Exons of the gene's MANE Select transcript (release v1.5), from NCBI and EMBL-EBI, on the GRCh38 reference genome.
Chromosome bands from UCSC's GRCh38 ideogram (2022-10-29).
Nearby genes from Ensembl release 116, on GRCh38.
Exons make up 2.3 kb of the gene's 11.8 kb; 1,638 of those bases code for the protein.

positions in RTN2 where ClinVar classes a change as pathogenic or likely pathogenic
None of them falls in a region short reads find hard.
A whole genome covers all 11.8 kb of RTN2, introns included, not only the 2.3 kb of exons.
