Variant summary

Our verdict is Benign. Variant got -21 ACMG points: 0P and 21B. BP4_Strong BP6_Very_Strong BP7 BS1 BS2

The NM_001277115.2(DNAH11):​c.13263G>C​(p.Pro4421=) variant causes a synonymous change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0112 in 1,613,828 control chromosomes in the GnomAD database, including 166 homozygotes. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Benign (★★). Synonymous variant affecting the same amino acid position (i.e. P4421P) has been classified 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 -21 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.61).
• BP6: Variant 7-21900080-G-C is Benign according to our data. Variant chr7-21900080-G-C is described in ClinVar as [Benign]. Clinvar id is 163129.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr7-21900080-G-C is described in Lovd as [Likely_benign].
• BP7: Synonymous conserved (PhyloP=-1.82 with no splicing effect.
• BS1: Variant frequency is greater than expected in population nfe. gnomad4 allele frequency = 0.0105 (1594/152240) while in subpopulation NFE AF= 0.0139 (945/68020). AF 95% confidence interval is 0.0132. There are 22 homozygotes in gnomad4. There are 853 alleles in male gnomad4 subpopulation. Median coverage is 33. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd4 at 22 AR gene
