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

Verdict is Benign. Variant got -20 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.0068701804).
• BP6: Variant 15-101010802-C-A is Benign according to our data. Variant chr15-101010802-C-A is described in ClinVar as [Benign]. Clinvar id is 719736.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BS1: Variant frequency is greater than expected in population sas. gnomad4 allele frequency = 0.00864 (1315/152260) while in subpopulation SAS AF= 0.0159 (77/4830). AF 95% confidence interval is 0.0131. There are 11 homozygotes in gnomad4. There are 683 alleles in male gnomad4 subpopulation. Median coverage is 31. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd4 at 11 AR gene
