Genes affected

LCN12 (HGNC:28733): (lipocalin 12) Members of the lipocalin family, such as LCN12, 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

Dec 21, 2023

The c.164C>T (p.P55L) alteration is located in exon 2 (coding exon 2) of the LCN12 gene. This alteration results from a C to T substitution at nucleotide position 164, causing the proline (P) at amino acid position 55 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
