Genes affected

RBP2 (HGNC:9920): (retinol binding protein 2) This gene encodes an abundant protein present in the small intestinal epithelium. It is thought to participate in the uptake and/or intracellular metabolism of vitamin A. Vitamin A is a fat-soluble vitamin necessary for growth, reproduction, differentiation of epithelial tissues, and vision. This protein may also modulate the supply of retinoic acid to the nuclei of endometrial cells during the menstrual cycle. [provided by RefSeq, Aug 2015]

The c.176G>A (p.R59H) alteration is located in exon 2 (coding exon 2) of the RBP2 gene. This alteration results from a G to A substitution at nucleotide position 176, causing the arginine (R) at amino acid position 59 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
