Genes affected

LRRC17 (HGNC:16895): (leucine rich repeat containing 17) Predicted to be involved in bone marrow development and negative regulation of osteoclast differentiation. Predicted to be active in extracellular matrix and extracellular space. [provided by Alliance of Genome Resources, Apr 2022]

LRRC17 links:

FBXL13 (HGNC:21658): (F-box and leucine rich repeat protein 13) Members of the F-box protein family, such as FBXL13, are characterized by an approximately 40-amino acid F-box motif. SCF complexes, formed by SKP1 (MIM 601434), cullin (see CUL1; MIM 603134), and F-box proteins, act as protein-ubiquitin ligases. F-box proteins interact with SKP1 through the F box, and they interact with ubiquitination targets through other protein interaction domains (Jin et al., 2004 [PubMed 15520277]).[supplied by OMIM, Mar 2008]

Ambry Genetics

Dec 06, 2022

The c.341A>G (p.Q114R) alteration is located in exon 2 (coding exon 1) of the LRRC17 gene. This alteration results from a A to G substitution at nucleotide position 341, causing the glutamine (Q) at amino acid position 114 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
