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]

Ambry Genetics

Nov 25, 2024

The c.3806C>T (p.T1269M) alteration is located in exon 26 (coding exon 26) of the MYBBP1A gene. This alteration results from a C to T substitution at nucleotide position 3806, causing the threonine (T) at amino acid position 1269 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
