Genes affected

LRCH1 (HGNC:20309): (leucine rich repeats and calponin homology domain containing 1) This gene encodes a protein with a leucine-rich repeat and a calponin homology domain. Polymorphism in this gene may be associated with susceptibililty to knee osteoarthritis. Alternative splicing results in multiple transcript variants encoding different isoforms.

The c.157G>A (p.G53R) alteration is located in exon 1 (coding exon 1) of the LRCH1 gene. This alteration results from a G to A substitution at nucleotide position 157, causing the glycine (G) at amino acid position 53 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
