Variant summary

Our verdict is Benign. The variant received -20 ACMG points: 0P and 20B. BP4_StrongBP6_Very_StrongBS1BS2

The NM_178452.6(DNAAF1):c.1750G>A(p.Asp584Asn) variant causes a missense change. The variant allele was found at a frequency of 0.00116 in 1,614,088 control chromosomes in the GnomAD database, including 11 homozygotes. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Likely benign (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. D584H) has been classified as Uncertain significance.

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 -20 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.0046860278).

BP6

Variant 16-84175984-G-A is Benign according to our data. Variant chr16-84175984-G-A is described in ClinVar as Benign/Likely_benign. ClinVar VariationId is 262946.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

BS1

Variant frequency is greater than expected in population eas. GnomAd4 allele frequency = 0.00104 (158/152284) while in subpopulation EAS AF = 0.00983 (51/5186). AF 95% confidence interval is 0.00768. There are 0 homozygotes in GnomAd4. There are 107 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check.

BS2

High Homozygotes in GnomAdExome4 at 11 AR,AD gene
