Genes affected
RBBP5 (HGNC:9888): (RB binding protein 5, histone lysine methyltransferase complex subunit) This gene encodes a ubiquitously expressed nuclear protein which belongs to a highly conserved subfamily of WD-repeat proteins. The encoded protein binds directly to retinoblastoma protein, which regulates cell proliferation. It interacts preferentially with the underphosphorylated retinoblastoma protein via the E1A-binding pocket B. Three alternatively spliced transcript variants that encode different protein isoforms have been described for this gene. [provided by RefSeq, Jul 2010]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 26, 2023The c.622C>T (p.R208W) alteration is located in exon 6 (coding exon 6) of the RBBP5 gene. This alteration results from a C to T substitution at nucleotide position 622, causing the arginine (R) at amino acid position 208 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
