Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the SLC12A5 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: Mediates electroneutral potassium-chloride cotransport in mature neurons and is required for neuronal Cl(-) homeostasis. As major extruder of intracellular chloride, it establishes the low neuronal Cl(-) levels required for chloride influx after binding of GABA-A and glycine to their receptors, with subsequent hyperpolarization and neuronal inhibition (By similarity). Involved in the regulation of dendritic spine formation and maturation (PubMed:24668262). {ECO:0000250|UniProtKB:Q63633, ECO:0000269|PubMed:24668262}.
• Disease: DISEASE: Epilepsy, idiopathic generalized 14 (EIG14) [MIM:616685]: An autosomal dominant form of idiopathic generalized epilepsy, a disorder characterized by recurring generalized seizures in the absence of detectable brain lesions and/or metabolic abnormalities. Generalized seizures arise diffusely and simultaneously from both hemispheres of the brain. Seizure types include juvenile myoclonic seizures, absence seizures, and generalized tonic-clonic seizures. {ECO:0000269|PubMed:24668262, ECO:0000269|PubMed:24928908, ECO:0000269|PubMed:26528127}. Note=Disease susceptibility is associated with variations affecting the gene represented in this entry.
