Genes affected

RBP5 (HGNC:15847): (retinol binding protein 5) The protein encoded by this gene is a cellular retinol-binding protein expressed highly in kidney and liver. Down-regulation of the encoded protein in hepatocellular carcinoma was associated with large tumor size and poor patient survival rates. [provided by RefSeq, Jul 2016]

May 18, 2023

The c.232G>T (p.V78L) alteration is located in exon 2 (coding exon 2) of the RBP5 gene. This alteration results from a G to T substitution at nucleotide position 232, causing the valine (V) at amino acid position 78 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
