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.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 15, 2022The c.92A>G (p.N31S) alteration is located in exon 2 (coding exon 2) of the LECT2 gene. This alteration results from a A to G substitution at nucleotide position 92, causing the asparagine (N) at amino acid position 31 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
