Genes affected

XPO5 (HGNC:17675): (exportin 5) This gene encodes a member of the karyopherin family that is required for the transport of small RNAs and double-stranded RNA-binding proteins from the nucleus to the cytoplasm. The encoded protein translocates cargo through the nuclear pore complex in a RanGTP-dependent process. [provided by RefSeq, Aug 2011]

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]

ACMG classification

Verdict is Benign. Variant got -14 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.92).
• BP6: Variant 6-43524307-G-A is Benign according to our data. Variant chr6-43524307-G-A is described in ClinVar as [Likely_benign]. Clinvar id is 1317903.Status of the report is criteria_provided_single_submitter, 1 stars.
• BS1: Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.00562 (840/149368) while in subpopulation AFR AF= 0.0193 (781/40450). AF 95% confidence interval is 0.0182. There are 10 homozygotes in gnomad4. There are 380 alleles in male gnomad4 subpopulation. Median coverage is 31. This position pass quality control queck.
• BS2: High AC in GnomAd4 at 840 AD gene.
