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.

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -1 ACMG points.

PM2

Very rare variant in population databases, with high coverage;

BP4

Computational evidence support a benign effect (MetaRNN=0.13479808).

BS1

Variant frequency is greater than expected in population sas. gnomad4_exome allele frequency = 0.0000445 (65/1461826) while in subpopulation SAS AF= 0.000185 (16/86254). AF 95% confidence interval is 0.000115. There are 1 homozygotes in gnomad4_exome. There are 38 alleles in male gnomad4_exome subpopulation. Median coverage is 30. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

Collection Method: clinical testing

This sequence change replaces serine with leucine at codon 5 of the LRRK1 protein (p.Ser5Leu). The serine residue is weakly conserved and there is a large physicochemical difference between serine and leucine. This variant is present in population databases (rs748591648, ExAC 0.01%). 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 are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0"). 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. -
