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.41C>G (p.A14G) alteration is located in exon 1 (coding exon 1) of the LRCH1 gene. This alteration results from a C to G substitution at nucleotide position 41, causing the alanine (A) at amino acid position 14 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
