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.670A>C (p.K224Q) alteration is located in exon 4 (coding exon 4) of the LRCH1 gene. This alteration results from a A to C substitution at nucleotide position 670, causing the lysine (K) at amino acid position 224 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
