Genes affected
DNAAF1 (HGNC:30539): (dynein axonemal assembly factor 1) The protein encoded by this gene is cilium-specific and is required for the stability of the ciliary architecture. It is involved in the regulation of microtubule-based cilia and actin-based brush border microvilli. Mutations in this gene are associated with primary ciliary dyskinesia-13. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jan 2016]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -9 ACMG points.

BP4
Computational evidence support a benign effect (MetaRNN=0.013773799).
BP6
Variant 16-84170182-C-A is Benign according to our data. Variant chr16-84170182-C-A is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 216831.
BS1
Variant frequency is greater than expected in population nfe. GnomAd4 allele frequency = 0.00081 (123/151836) while in subpopulation NFE AF = 0.00147 (100/67924). AF 95% confidence interval is 0.00124. There are 0 homozygotes in GnomAd4. There are 53 alleles in the male GnomAd4 subpopulation. Median coverage is 31. This position passed quality control check.
