Inheritance pattern


Summary of published research, and additional commentary

Although Polyphen 2 predicts a damaging effect, this variant is very common (20% allele frequency in PGP+public genomes, 40% in 1000 genomes data). Other variants in this gene are implicated in causing diseases (hypokalemic periodic paralysis, malignant hyperthermia) in a dominant manner, but this variant is presumed benign due to its very common allele frequency.

Allele frequency

  • T @ chr1:201052310: 27.3% (2935/10758) in EVS
  • TGC @ chr1:199318932: 20.3% (26/128) in GET-Evidence
  • Frequency shown in summary reports: 27.3% (2935/10758)
