Variant summary

Our verdict is Benign. Variant got -15 ACMG points: 2P and 17B. PM2 BP4_Strong BP6_Very_Strong BP7 BS1

The NM_001277115.2(DNAH11):c.10350C>G(p.Thr3450=) variant causes a synonymous change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000261 in 1,607,444 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 (★★). Synonymous variant affecting the same amino acid position (i.e. T3450T) 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.

LOC124901599 (HGNC:):

ACMG classification

Verdict is Benign. Variant got -15 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 7-21816484-C-G is Benign according to our data. Variant chr7-21816484-C-G is described in ClinVar as [Likely_benign]. Clinvar id is 416429.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BP7: Synonymous conserved (PhyloP=-2.99 with no splicing effect.
• BS1: Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.00143 (217/152172) while in subpopulation AFR AF= 0.00501 (208/41516). AF 95% confidence interval is 0.00445. There are 0 homozygotes in gnomad4. There are 100 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.

Benign, criteria provided, single submitter	clinical testing	Invitae	Jan 31, 2024	- -
Likely benign, criteria provided, single submitter	clinical testing	Ambry Genetics	Apr 11, 2022	This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
