Genes affected
SLC12A5 (HGNC:13818): (solute carrier family 12 member 5) K-Cl cotransporters are proteins that lower intracellular chloride concentrations below the electrochemical equilibrium potential. The protein encoded by this gene is an integral membrane K-Cl cotransporter that can function in either a net efflux or influx pathway, depending on the chemical concentration gradients of potassium and chloride. The encoded protein can act as a homomultimer, or as a heteromultimer with other K-Cl cotransporters, to maintain chloride homeostasis in neurons. Alternative splicing results in two transcript variants encoding different isoforms. [provided by RefSeq, Sep 2008]

Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Oct 17, 2022 | For these reasons, this variant has been classified as Pathogenic. ClinVar contains an entry for this variant (Variation ID: 934757). This variant has not been reported in the literature in individuals affected with SLC12A5-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change creates a premature translational stop signal (p.Cys8*) in the SLC12A5 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in SLC12A5 are known to be pathogenic (PMID: 26333769, 27436767). - |
