Genes affected
TCOF1 (HGNC:11654): (treacle ribosome biogenesis factor 1) This gene encodes a nucleolar protein with a LIS1 homology domain. The protein is involved in ribosomal DNA gene transcription through its interaction with upstream binding factor (UBF). Mutations in this gene have been associated with Treacher Collins syndrome, a disorder which includes abnormal craniofacial development. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Sep 2008]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -13 ACMG points.

BP4
Computational evidence support a benign effect (MetaRNN=0.017512083).
BP6
Variant 5-150379325-C-G is Benign according to our data. Variant chr5-150379325-C-G is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 225484.
BS1
Variant frequency is greater than expected in population eas. GnomAd4 allele frequency = 0.0000459 (7/152346) while in subpopulation EAS AF = 0.00135 (7/5184). AF 95% confidence interval is 0.000633. There are 0 homozygotes in GnomAd4. There are 2 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.
BS2
High AC in GnomAd4 at 7 AD gene.
