Genes affected

POLR1D (HGNC:20422): (RNA polymerase I and III subunit D) The protein encoded by this gene is a component of the RNA polymerase I and RNA polymerase III complexes, which function in the synthesis of ribosomal RNA precursors and small RNAs, respectively. Mutations in this gene are a cause of Treacher Collins syndrome (TCS), a craniofacial development disorder. Alternative splicing results in multiple transcript variants.

ACMG classification

Verdict is Benign. Variant got -8 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.91).
• BS1: Variant frequency is greater than expected in population nfe. gnomad4 allele frequency = 0.000184 (28/152060) while in subpopulation NFE AF= 0.000397 (27/68000). AF 95% confidence interval is 0.00028. There are 0 homozygotes in gnomad4. There are 10 alleles in male gnomad4 subpopulation. This position pass quality control queck.
