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]

Ambry Genetics

Aug 26, 2022

The c.121G>A (p.G41R) alteration is located in exon 2 (coding exon 2) of the LCN8 gene. This alteration results from a G to A substitution at nucleotide position 121, causing the glycine (G) at amino acid position 41 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
