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 Benign. Variant got -20 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.002060622).
• BP6: Variant 7-21901198-G-A is Benign according to our data. Variant chr7-21901198-G-A is described in ClinVar as [Likely_benign]. Clinvar id is 226581.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr7-21901198-G-A is described in Lovd as [Likely_benign].
• BS1: Variant frequency is greater than expected in population mid. gnomad4_exome allele frequency = 0.00363 (5312/1461600) while in subpopulation MID AF= 0.00433 (25/5768). AF 95% confidence interval is 0.00308. There are 43 homozygotes in gnomad4_exome. There are 2634 alleles in male gnomad4_exome subpopulation. Median coverage is 33. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd at 7 AR gene
