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 GeneticsOct 12, 2022The c.146C>T (p.A49V) 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 146, causing the alanine (A) at amino acid position 49 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
