Variant summary

Our verdict is Likely benign. Variant got -1 ACMG points: 2P and 3B. PM2 BP4_Moderate BP6

The NM_001369.3(DNAH5):​c.632C>T​(p.Ser211Leu) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000421 in 1,613,856 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 14/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Synonymous variant affecting the same amino acid position (i.e. S211S) has been classified as Likely benign.

Genes affected

DNAH5 (HGNC:2950): (dynein axonemal heavy chain 5) This gene encodes a dynein protein, which is part of a microtubule-associated motor protein complex consisting of heavy, light, and intermediate chains. This protein is an axonemal heavy chain dynein. It functions as a force-generating protein with ATPase activity, whereby the release of ADP is thought to produce the force-producing power stroke. Mutations in this gene cause primary ciliary dyskinesia type 3, as well as Kartagener syndrome, which are both diseases due to ciliary defects. [provided by RefSeq, Oct 2009]

ACMG classification

Verdict is Likely_benign. Variant got -1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.076134175).
• BP6: Variant 5-13922135-G-A is Benign according to our data. Variant chr5-13922135-G-A is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 570850.We mark this variant Likely_benign, oryginal submissions are: {Benign=1, Uncertain_significance=2}.

Uncertain significance, criteria provided, single submitter	clinical testing	Ambry Genetics	Oct 29, 2021	The p.S211L variant (also known as c.632C>T), located in coding exon 5 of the DNAH5 gene, results from a C to T substitution at nucleotide position 632. The serine at codon 211 is replaced by leucine, an amino acid with dissimilar properties. This amino acid position is conserved. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
