Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the DST gene is commonly pathogenic or not. These statistics are base on transcript: NM_001374736.1. Only rare variants are included in the table.

In the table, we include only reliable ClinVar variants with their consequences to MANE Select, Mane Plus Clinical transcripts, or transcripts with TSL equals 1. Click the count to view the source variants.

Warning: slight differences between displayed counts and the number of variants in ClinVar may occur, primarily due to (1) the application of a different transcript and/or consequence by our variant effect predictor or (2) differences in clinical significance: we classify Benign/Likely benign variants as Likely benign and Pathogenic/Likely pathogenic variants as Likely pathogenic.

• Function: FUNCTION: Cytoskeletal linker protein. Acts as an integrator of intermediate filaments, actin and microtubule cytoskeleton networks. Required for anchoring either intermediate filaments to the actin cytoskeleton in neural and muscle cells or keratin- containing intermediate filaments to hemidesmosomes in epithelial cells. The proteins may self-aggregate to form filaments or a two- dimensional mesh. Regulates the organization and stability of the microtubule network of sensory neurons to allow axonal transport. Mediates docking of the dynein/dynactin motor complex to vesicle cargos for retrograde axonal transport through its interaction with TMEM108 and DCTN1 (By similarity). {ECO:0000250|UniProtKB:Q91ZU6}.; FUNCTION: Isoform 6: required for bundling actin filaments around the nucleus. {ECO:0000250, ECO:0000269|PubMed:10428034, ECO:0000269|PubMed:12482924, ECO:0000269|PubMed:19403692}.
• Disease: DISEASE: Neuropathy, hereditary sensory and autonomic, 6 (HSAN6) [MIM:614653]: A form of hereditary sensory and autonomic neuropathy, a genetically and clinically heterogeneous group of disorders characterized by degeneration of dorsal root and autonomic ganglion cells, and by sensory and/or autonomic abnormalities. HSAN6 is a severe autosomal recessive disorder characterized by neonatal hypotonia, respiratory and feeding difficulties, lack of psychomotor development, and autonomic abnormalities including labile cardiovascular function, lack of corneal reflexes leading to corneal scarring, areflexia, and absent axonal flare response after intradermal histamine injection. {ECO:0000269|PubMed:22522446}. Note=The disease is caused by mutations affecting the gene represented in this entry.; DISEASE: Epidermolysis bullosa simplex, autosomal recessive 2 (EBSB2) [MIM:615425]: A form of epidermolysis bullosa, a dermatologic disorder characterized by localized blistering on the dorsal, lateral and plantar surfaces of the feet. EBSB2 is characterized by trauma-induced blistering mainly occurring on the feet and ankles. Ultrastructural analysis of skin biopsy shows abnormal hemidesmosomes with poorly formed inner plaques. {ECO:0000269|PubMed:20164846, ECO:0000269|PubMed:22113475}. Note=The disease is caused by mutations affecting the gene represented in this entry.
