Genes affected

POLR1C (HGNC:20194): (RNA polymerase I and III subunit C) The protein encoded by this gene is a subunit of both RNA polymerase I and RNA polymerase III complexes. The encoded protein is part of the Pol core element. Mutations in this gene have been associated with Treacher Collins syndrome (TCS) and hypomyelinating leukodystrophy 11. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jan 2016]

(HGNC:):

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.6).
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.181 is higher than 0.05.
