Description

This sequence change replaces proline with leucine at codon 16 of the HCN4 protein (p.Pro16Leu). The proline residue is moderately conserved and there is a moderate physicochemical difference between proline and leucine. 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 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.
