Invitae RCV001228475 SCV001400875 uncertain significance Brugada syndrome 8 2021-08-24 criteria provided, single submitter clinical testing This sequence change replaces glutamic acid with glutamine at codon 30 of the HCN4 protein (p.Glu30Gln). The glutamic acid residue is moderately conserved and there is a small physicochemical difference between glutamic acid and glutamine. The frequency data for this variant in the population databases is considered unreliable, as metrics indicate insufficient coverage at this position in the ExAC database. This variant has not been reported in the literature in individuals affected with HCN4-related conditions. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance.
