Variant summary

Our verdict is Benign. The variant received -13 ACMG points: 0P and 13B. BP4_StrongBP6BS1BS2

The NM_001277115.2(DNAH11):c.661A>T(p.Met221Leu) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000693 in 1,588,018 control chromosomes in the GnomAD database, including 16 homozygotes. In-silico tool predicts a benign outcome for this variant. 15/20 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. M221I) 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

Classification was made for transcript

Our verdict: Benign. The variant received -13 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.005828619).

BP6

Variant 7-21558967-A-T is Benign according to our data. Variant chr7-21558967-A-T is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 215427.

BS1

Variant frequency is greater than expected in population sas. GnomAd4 allele frequency = 0.000584 (89/152330) while in subpopulation SAS AF = 0.00973 (47/4832). AF 95% confidence interval is 0.00752. There are 2 homozygotes in GnomAd4. There are 57 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check.

BS2

High Homozygotes in GnomAd4 at 2 AR,AD gene
