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.

Feb 07, 2023

The c.852T>G (p.F284L) alteration is located in exon 6 (coding exon 6) of the LRCH1 gene. This alteration results from a T to G substitution at nucleotide position 852, causing the phenylalanine (F) at amino acid position 284 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
