Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the DAB1 gene is commonly pathogenic or not.

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: Adapter molecule functioning in neural development. May regulate SIAH1 activity. {ECO:0000250|UniProtKB:P97318}.
• Disease: DISEASE: Spinocerebellar ataxia 37 (SCA37) [MIM:615945]: A form of spinocerebellar ataxia, a clinically and genetically heterogeneous group of cerebellar disorders. Patients show progressive incoordination of gait and often poor coordination of hands, speech and eye movements, due to degeneration of the cerebellum with variable involvement of the brainstem and spinal cord. SCA37 is an autosomal dominant form characterized by adult-onset of slowly progressive gait instability, frequent falls, and dysarthria associated with cerebellar atrophy on brain imaging. {ECO:0000269|PubMed:28686858}. Note=The disease is caused by mutations affecting the gene represented in this entry.
