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]

ACMG classification

Classification was made for transcript

Our verdict: Pathogenic. The variant received 10 ACMG points.

PVS1

Splicing +-2 bp (donor or acceptor) variant, product NOT destroyed by NMD, known LOF gene, truncates exone, which is 0.04894295 fraction of the gene. Cryptic splice site detected, with MaxEntScore 5, offset of 0 (no position change), new splice context is: gcaGTaaga. Cryptic site results in inframe change. If cryptic site found is not functional and variant results in exon loss, it results in frameshift change.

PP5

Variant 15-34240659-AC-A is Pathogenic according to our data. Variant chr15-34240659-AC-A is described in ClinVar as Pathogenic. ClinVar VariationId is 436730.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
