Genes affected
CRABP2 (HGNC:2339): (cellular retinoic acid binding protein 2) This gene encodes a member of the retinoic acid (RA, a form of vitamin A) binding protein family and lipocalin/cytosolic fatty-acid binding protein family. The protein is a cytosol-to-nuclear shuttling protein, which facilitates RA binding to its cognate receptor complex and transfer to the nucleus. It is involved in the retinoid signaling pathway, and is associated with increased circulating low-density lipoprotein cholesterol. Alternatively spliced transcript variants encoding the same protein have been found for this gene.[provided by RefSeq, Dec 2010]

not specified Uncertain:1
| Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Aug 15, 2023 | The c.312G>C (p.E104D) alteration is located in exon 3 (coding exon 3) of the CRABP2 gene. This alteration results from a G to C substitution at nucleotide position 312, causing the glutamic acid (E) at amino acid position 104 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
