Genes affected
DNAI1 (HGNC:2954): (dynein axonemal intermediate chain 1) This gene encodes a member of the dynein intermediate chain family. The encoded protein is part of the dynein complex in respiratory cilia. The inner- and outer-arm dyneins, which bridge between the doublet microtubules in axonemes, are the force-generating proteins responsible for the sliding movement in axonemes. The intermediate and light chains, thought to form the base of the dynein arm, help mediate attachment and may also participate in regulating dynein activity. Mutations in this gene result in abnormal ciliary ultrastructure and function associated with primary ciliary dyskinesia and Kartagener syndrome. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jul 2013]

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -14 ACMG points.

BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.51).
BP6
Variant 9-34489358-A-G is Benign according to our data. Variant chr9-34489358-A-G is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 226608.We mark this variant Likely_benign, oryginal submissions are: {Benign=5, Uncertain_significance=1}.
BP7
Synonymous conserved (PhyloP=0.587 with no splicing effect.
BA1
GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.0527 is higher than 0.05.
