Genes affected

LRRK1 (HGNC:18608): (leucine rich repeat kinase 1) This gene encodes a multi-domain protein that is a leucine-rich repeat kinase and a GDP/GTP binding protein. The encoded protein is thought to play a role in the regulation of bone mass. Mice lacking a similar gene showed severe osteopetrosis, increased bone mineralization and decreased bone resorption.

This sequence change replaces proline, which is neutral and non-polar, with serine, which is neutral and polar, at codon 24 of the LRRK1 protein (p.Pro24Ser). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with LRRK1-related conditions. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. 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. -
