Sarah Leigh (Genomics England Curator)

For-review tag has been added as it maybe appropriate to change the MOI to BOTH monoallelic and biallelic, autosomal or pseudoautosomal at the next major review, to ensure that de novo heterozgous variants are identified.

Associated with Agenesis of the corpus callosum with peripheral neuropathy 218000 in OMIM and as confirmed Gen2Phen gene. At least 10 biallelic variants were reported in at least 10 unrelated cases. 9/10 of these variants was terminating (PMID 12368912, 16606917, 17893295). Three de novo heterozygous missense variants have been identified in four unrelated cases with a milder phenotype of early- onset progressive Charcot- Marie-tooth disease (CMT) with or without spasticity (intermediate CMT)(PMID 31439721, 27485015). The authors of PMID 31439721 suggest that "autosomal- dominant inheritance of SLC12A6 variants also needs to be considered in patients with early- onset neuropathies". Furthermore, it will be important to understand the functional differences between the variants, as PMID 27485015 reported variant - p.Thr991Ala, resulted in increased potassium influx in Xenopus oocytes (gain-of-function), while the other missense variants identified so far had a loss-of-function effect in varying degrees (PMID 31439721).
