Genes affected
MYBBP1A (HGNC:7546): (MYB binding protein 1a) This gene encodes a nucleolar transcriptional regulator that was first identified by its ability to bind specifically to the Myb proto-oncogene protein. The encoded protein is thought to play a role in many cellular processes including response to nucleolar stress, tumor suppression and synthesis of ribosomal DNA. Alternate splicing results in multiple transcript variants. [provided by RefSeq, Sep 2013]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 03, 2024The c.3676G>A (p.G1226R) alteration is located in exon 26 (coding exon 26) of the MYBBP1A gene. This alteration results from a G to A substitution at nucleotide position 3676, causing the glycine (G) at amino acid position 1226 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
