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.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 04, 2023The c.863G>A (p.S288N) alteration is located in exon 6 (coding exon 6) of the LRCH1 gene. This alteration results from a G to A substitution at nucleotide position 863, causing the serine (S) at amino acid position 288 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
