Genes affected
RTBDN (HGNC:30310): (retbindin) This gene was first identified in a study of human eye tissues. The protein encoded by this gene is preferentially expressed in the retina and may play a role in binding retinoids and other carotenoids as it shares homology with riboflavin binding proteins. Alternative splicing results in multiple transcript variants and protein isoforms. [provided by RefSeq, Jul 2012]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 18, 2023The c.571G>C (p.G191R) alteration is located in exon 7 (coding exon 7) of the RTBDN gene. This alteration results from a G to C substitution at nucleotide position 571, causing the glycine (G) at amino acid position 191 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
