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.514G>A (p.A172T) alteration is located in exon 3 (coding exon 3) of the LRCH1 gene. This alteration results from a G to A substitution at nucleotide position 514, causing the alanine (A) at amino acid position 172 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
