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]

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]

ACMG classification

Verdict is Uncertain_significance. Variant got 1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.28272063).

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.181C>T (p.H61Y) alteration is located in exon 2 (coding exon 1) of the LRRC17 gene. This alteration results from a C to T substitution at nucleotide position 181, causing the histidine (H) at amino acid position 61 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
