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 Uncertain_significance. Variant got 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.40938774).
• BP6: Variant 7-21711724-G-A is Benign according to our data. Variant chr7-21711724-G-A is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 569927.We mark this variant Likely_benign, oryginal submissions are: {Benign=1, Uncertain_significance=1}.

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.6847G>A (p.A2283T) alteration is located in exon 42 (coding exon 42) of the DNAH11 gene. This alteration results from a G to A substitution at nucleotide position 6847, causing the alanine (A) at amino acid position 2283 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
