Variant summary

Our verdict is Pathogenic. Variant got 16 ACMG points: 16P and 0B. PVS1PP5_Very_Strong

The NM_001365088.1(SLC12A6):​c.963C>A​(p.Tyr321*) variant causes a stop gained change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000411 in 1,460,740 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Likely pathogenic (★★). Synonymous variant affecting the same amino acid position (i.e. Y321Y) has been classified as Benign. Variant results in nonsense mediated mRNA decay.

Genes affected
SLC12A6 (HGNC:10914): (solute carrier family 12 member 6) This gene is a member of the K-Cl cotransporter (KCC) family. K-Cl cotransporters are integral membrane proteins that lower intracellular chloride concentrations below the electrochemical equilibrium potential. The proteins encoded by this gene are activated by cell swelling induced by hypotonic conditions. Alternate splicing results in multiple transcript variants encoding different isoforms. Mutations in this gene are associated with agenesis of the corpus callosum with peripheral neuropathy. [provided by RefSeq, Jul 2008]

Pathogenic, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpMay 13, 2023This sequence change creates a premature translational stop signal (p.Tyr321*) in the SLC12A6 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in SLC12A6 are known to be pathogenic (PMID: 12368912, 16606917). For these reasons, this variant has been classified as Pathogenic. ClinVar contains an entry for this variant (Variation ID: 370595). This variant has not been reported in the literature in individuals affected with SLC12A6-related conditions. This variant is present in population databases (no rsID available, gnomAD 0.0009%). -
