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 GeneticsMay 09, 2024The c.1550G>C (p.G517A) alteration is located in exon 5 (coding exon 4) of the RBAK gene. This alteration results from a G to C substitution at nucleotide position 1550, causing the glycine (G) at amino acid position 517 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
