Variant summary

Our verdict is Pathogenic. Variant got 10 ACMG points: 10P and 0B. PS1PM2PP3_Strong

The ENST00000311014.11(DNAI2):ā€‹c.1420G>Cā€‹(p.Gly474Arg) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.00000137 in 1,461,616 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. 12/21 in silico tools predict a damaging outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another nucleotide change resulting in same amino acid change has been previously reported as Pathogenicin ClinVar. Synonymous variant affecting the same amino acid position (i.e. G474G) has been classified as Likely benign.

Genes affected
DNAI2 (HGNC:18744): (dynein axonemal intermediate chain 2) The protein encoded by this gene belongs to the dynein intermediate chain family, and is part of the dynein complex of respiratory cilia and sperm flagella. Mutations in this gene are associated with primary ciliary dyskinesia type 9. Alternatively spliced transcript variants encoding different isoforms have been noted for this gene.
