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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 30, 2023The c.406C>T (p.R136W) alteration is located in exon 5 (coding exon 5) of the RTBDN gene. This alteration results from a C to T substitution at nucleotide position 406, causing the arginine (R) at amino acid position 136 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
