Variant summary

Our verdict is Pathogenic. The variant received 14 ACMG points: 14P and 0B. PS3PP3_ModeratePP5_Very_Strong

The NM_012144.4(DNAI1):c.1543G>A(p.Gly515Ser) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.0000136 in 1,614,022 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Likely pathogenic (★★). ClinVar reports functional evidence for this variant: "SCV002709301: ex vivo cultures of the patient's epithelial airway found his cilia were immotile (Chhin B et al. PLoS Genet. 2009" and additional evidence is available in ClinVar. Synonymous variant affecting the same amino acid position (i.e. G515G) has been classified as Likely benign.

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]
