Genes affected

LCN1 (HGNC:6525): (lipocalin 1) This gene encodes a member of the lipocalin family of small secretory proteins. Lipocalins are extracellular transport proteins that bind to a variety of hydrophobic ligands. The encoded protein is the primary lipid binding protein in tears and is overproduced in response to multiple stimuli including infection and stress. The encoded protein may be a marker for chromosome aneuploidy as well as an autoantigen in Sjogren's syndrome. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene, and two pseudogenes of this gene are also located on the long arm of chromosome 9.

The c.464G>A (p.R155H) alteration is located in exon 5 (coding exon 5) of the LCN1 gene. This alteration results from a G to A substitution at nucleotide position 464, causing the arginine (R) at amino acid position 155 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
