Genes affected

LCN9 (HGNC:17442): (lipocalin 9) Members of the lipocalin family, such as LCN9, 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

Jan 10, 2023

The c.146G>C (p.R49P) alteration is located in exon 2 (coding exon 2) of the LCN9 gene. This alteration results from a G to C substitution at nucleotide position 146, causing the arginine (R) at amino acid position 49 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
