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.

CDCA7L (HGNC:30777): (cell division cycle associated 7 like) Acts upstream of or within positive regulation of cell population proliferation. Located in cytosol; fibrillar center; and nucleoplasm. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Verdict is Uncertain_significance. Variant got 5 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PM4: Stoplost variant in NM_001277115.2 Downstream stopcodon found after 55 codons.
• PP5: Variant 7-21901224-GGCTGGAGTGGCTCTGCTTCTAGAAGCGTAAGGTAACACTGGCATTCCTCTAGCCTCT-G is Pathogenic according to our data. Variant chr7-21901224-GGCTGGAGTGGCTCTGCTTCTAGAAGCGTAAGGTAACACTGGCATTCCTCTAGCCTCT-G is described in ClinVar as [Pathogenic]. Clinvar id is 6476.Status of the report is no_assertion_criteria_provided, 0 stars.
