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 made for transcript

Verdict is Benign. Variant got -13 ACMG points.

BP4
Computational evidence support a benign effect (MetaRNN=0.0056365132).
BP6
Variant 16-84175952-T-C is Benign according to our data. Variant chr16-84175952-T-C is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 262945.We mark this variant Likely_benign, oryginal submissions are: {Likely_benign=2, Uncertain_significance=1}.
BS1
Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.00225 (342/152330) while in subpopulation AFR AF= 0.00794 (330/41562). AF 95% confidence interval is 0.00723. There are 2 homozygotes in gnomad4. There are 188 alleles in male gnomad4 subpopulation. Median coverage is 33. This position pass quality control queck.
BS2
High Homozygotes in GnomAd4 at 2 AR gene
