Genes affected

BDP1 (HGNC:13652): (B double prime 1, subunit of RNA polymerase III transcription initiation factor IIIB) The product of this gene is a subunit of the TFIIIB transcription initiation complex, which recruits RNA polymerase III to target promoters in order to initiate transcription. The encoded protein localizes to concentrated aggregates in the nucleus, and is required for transcription from all three types of polymerase III promoters. It is phosphorylated by casein kinase II during mitosis, resulting in its release from chromatin and suppression of polymerase III transcription. [provided by RefSeq, Jul 2008]

The c.215C>T (p.T72I) alteration is located in exon 2 (coding exon 2) of the BDP1 gene. This alteration results from a C to T substitution at nucleotide position 215, causing the threonine (T) at amino acid position 72 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
