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 -7 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.010172278).
• BP6: Variant 7-21591329-G-C is Benign according to our data. Variant chr7-21591329-G-C is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 359613.We mark this variant Likely_benign, oryginal submissions are: {Likely_benign=2, Uncertain_significance=1}.
• BS1: Variant frequency is greater than expected in population eas. gnomad4 allele frequency = 0.000328 (50/152314) while in subpopulation EAS AF= 0.00852 (44/5162). AF 95% confidence interval is 0.00653. There are 0 homozygotes in gnomad4. There are 27 alleles in male gnomad4 subpopulation. This position pass quality control queck.

Likely benign, criteria provided, single submitter	clinical testing	Ambry Genetics	Oct 06, 2022	This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
