Genes affected

LCN8 (HGNC:27038): (lipocalin 8) Members of the lipocalin family, such as LCN8, have a common structure consisting of an 8-stranded antiparallel beta-barrel that forms a cup-shaped ligand-binding pocket or calyx. Lipocalins generally bind small hydrophobic ligands and transport them to specific cells (Suzuki et al., 2004 [PubMed 15363845]).[supplied by OMIM, Aug 2009]

May 18, 2023

The c.355C>T (p.R119W) alteration is located in exon 5 (coding exon 5) of the LCN8 gene. This alteration results from a C to T substitution at nucleotide position 355, causing the arginine (R) at amino acid position 119 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
