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]

ACMG classification

Verdict is Benign. Variant got -20 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=2.523905E-5).
• BP6: Variant 5-71510822-T-A is Benign according to our data. Variant chr5-71510822-T-A is described in ClinVar as [Benign]. Clinvar id is 508086.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BA1: GnomAd4 highest subpopulation (SAS) allele frequency at 95% confidence interval = 0.532 is higher than 0.05.
