Genes affected

DNAH11 (HGNC:2942): (dynein axonemal heavy chain 11) This gene encodes a ciliary outer dynein arm protein and is a member of the dynein heavy chain family. It is a microtubule-dependent motor ATPase and has been reported to be involved in the movement of respiratory cilia. Mutations in this gene have been implicated in causing Kartagener Syndrome (a combination of situs inversus totalis and Primary Ciliary Dyskinesia (PCD), also called Immotile Cilia Syndrome 1 (ICS1)) and male sterility.

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -13 ACMG points.

BP4

Computational evidence support a benign effect (BayesDel_noAF=-0.83).

BP6

Variant 7-21655820-T-C is Benign according to our data. Variant chr7-21655820-T-C is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 257901.

BS1

Variant frequency is greater than expected in population mid. GnomAdExome4 allele frequency = 0.000389 (567/1457188) while in subpopulation MID AF = 0.0108 (62/5760). AF 95% confidence interval is 0.00862. There are 3 homozygotes in GnomAdExome4. There are 292 alleles in the male GnomAdExome4 subpopulation. Median coverage is 32. This position passed quality control check.

BS2

High Homozygotes in GnomAdExome4 at 3 AR,AD gene

c.4945-12T>C in intron 28 of DNAH11: This variant is not expected to have clinic al significance because a T>C change at this position does not diverge from the splice consensus sequence and is therefore unlikely to impact splicing. It has b een identified in 0.1% (48/53352) of European chromosomes by the Exome Aggregati on Consortium (ExAC, http://exac.broadinstitute.org; dbSNP rs141572016). -
