Genes affected
DNAAF3 (HGNC:30492): (dynein axonemal assembly factor 3) The protein encoded by this gene is required for the assembly of axonemal inner and outer dynein arms and plays a role in assembling dynein complexes for transport into cilia. Defects in this gene are a cause of primary ciliary dyskinesia type 2 (CILD2). Several transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, May 2012]

ACMG classification

Classification was made for transcript

Our verdict: Uncertain_significance. The variant received 1 ACMG points.

PM4
Stoplost variant in NM_001256715.2 Downstream stopcodon found after 31 codons.
BS1
Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.000481 (73/151668) while in subpopulation AFR AF = 0.00155 (64/41346). AF 95% confidence interval is 0.00124. There are 0 homozygotes in GnomAd4. There are 43 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting
