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.

Computational evidence support a benign effect (BayesDel_noAF=-0.75).

BP6

Variant 7-21704642-T-C is Benign according to our data. Variant chr7-21704642-T-C is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 257919.

BS1

Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.00435 (662/152302) while in subpopulation AFR AF = 0.015 (625/41556). AF 95% confidence interval is 0.0141. There are 5 homozygotes in GnomAd4. There are 323 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.

BS2

High Homozygotes in GnomAd4 at 5 AR,AD gene
