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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 03, 2022The c.74T>G (p.L25R) alteration is located in exon 1 (coding exon 1) of the LCN12 gene. This alteration results from a T to G substitution at nucleotide position 74, causing the leucine (L) at amino acid position 25 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
