Genes affected

LECT2 (HGNC:6550): (leukocyte cell derived chemotaxin 2) This gene encodes a secreted, 16 kDa protein that acts as a chemotactic factor to neutrophils and stimulates the growth of chondrocytes and osteoblasts. This protein has high sequence similarity to the chondromodulin repeat regions of the chicken myb-induced myeloid 1 protein. A polymorphism in this gene may be associated with rheumatoid arthritis.

The c.449A>G (p.Y150C) alteration is located in exon 4 (coding exon 4) of the LECT2 gene. This alteration results from a A to G substitution at nucleotide position 449, causing the tyrosine (Y) at amino acid position 150 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
