Variant summary

Our verdict is Benign. Variant got -14 ACMG points: 2P and 16B. PM2 BP4_Strong BP6_Very_Strong BS1

The NM_001277115.2(DNAH11):c.9598-16G>A variant causes a splice polypyrimidine tract, intron change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000344 in 1,605,252 control chromosomes in the GnomAD database, including 1 homozygotes. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Likely benign (★★).

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 -14 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.83).
• BP6: Variant 7-21786608-G-A is Benign according to our data. Variant chr7-21786608-G-A is described in ClinVar as [Likely_benign]. Clinvar id is 257941.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BS1: Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.002 (304/152296) while in subpopulation AFR AF= 0.0071 (295/41560). AF 95% confidence interval is 0.00643. There are 0 homozygotes in gnomad4. There are 131 alleles in male gnomad4 subpopulation. This position pass quality control queck.
