Genes affected
RBAK (HGNC:17680): (RB associated KRAB zinc finger) This gene encodes a nuclear protein which interacts with the tumor suppressor retinoblastoma 1. The two interacting proteins are thought to act as a transcriptional repressor for promoters which are activated by the E2F1 transcription factor. This protein contains a Kruppel-associated box (KRAB), which is a transcriptional repressor motif. Read-through transcripts that include exons from the downstream gene LOC389458 are expressed from this locus. [provided by RefSeq, Mar 2011]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 16, 2021The c.550G>T (p.G184W) alteration is located in exon 5 (coding exon 4) of the RBAK gene. This alteration results from a G to T substitution at nucleotide position 550, causing the glycine (G) at amino acid position 184 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
