Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
Jervell and Lange-Nielsen syndrome (JLNS) is an autosomal recessive (AR) disorder characterised by electrocardiographic QT prolongation, a pro-arrhythmic phenotype and sensorineural deafness. JLNS can reflect homozygous variants in the underlying KCNQ1/KCNE1, compound heterozygous variants in KCNQ1 or KCNE1, or combined heterozygous variants in KCNQ1 and KCNE1. KCNQ1 is the pore-forming subunit of the channel mediating slow delayed rectifier potassium currents, Iks; KCNE1 is an associated single transmembrane spanning β-subunit modulating KCNQ1 functional properties and cellular localisation. Experimental studies of isolated perfused mouse hearts at the cellular cardiomyocyte level and at the organ level in the genetic platforms of these conditions successfully recapitulated the clinical arrhythmic phenotypes and partially clarified their underlying mechanisms. Additionally, the utilization of iPSC cell platforms hold promise for investigating molecular mechanisms underlying both cardiac arrhythmic and sensorineural deafness phenotypes in patient-specific genetic backgrounds. This review summarises JLNS-related clinical genetics, physiological functions of KCNQ1 and KCNE1, and experimental models for its investigation.
