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

Verdict is Benign. Variant got -19 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.35).
• BP6: Variant 7-21784504-G-A is Benign according to our data. Variant chr7-21784504-G-A is described in ClinVar as [Likely_benign]. Clinvar id is 178731.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr7-21784504-G-A is described in Lovd as [Benign].
• BP7: Synonymous conserved (PhyloP=-0.298 with no splicing effect.
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.189 is higher than 0.05.

Leu3187Leu in exon 58 of DNAH11: This variant is not expected to have clinical s ignificance because it does not alter an amino acid residue and is not located w ithin the splice consensus sequence. It has been identified in 17.7% (695/3924) of African American chromosomes from a broad population by the NHLBI Exome Seque ncing Project (http://evs.gs.washington.edu/EVS; dbSNP rs6965750). -
