Primary ciliary dyskinesia 3 Uncertain:5
- -
This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score, this variant could not be ruled out of causing disease and therefore its association with disease required further investigation. A literature search was performed for the gene, cDNA change, and amino acid change (if applicable). No publications were found based on this search. This variant was therefore classified as a variant of unknown significance for this disease. -

The DNAH5 c.1715T>G (p.Leu572Trp) variant has been reported in one individual with Kartagener’s syndrome, but was not determined to be causative (Ozkavukcu S et al., PMID: 29402277). Additionally, DNAH5 c.1715T>G was published in an individual with situs inversus, but the protein change reported is p.Leu573*, so it is unclear if this is the same variant or a report of a distinct variant (Nöthe-Menchen T et al., PMID: 31638833). The highest population minor allele frequency in the population database genome aggregation database (v.2.1.1) is 0.1% in the European (non-Finnish) population, which is consistent with carrier status of primary ciliary dyskinesia. Computational predictors indicate that the variant is damaging, evidence that correlates with impact to DNAH5 function. Due to limited information, and based on ACMG/AMP guidelines for variant interpretation (Richards S et al., PMID: 25741868), the clinical significance of this variant is uncertain at this time. -

Primary ciliary dyskinesia Uncertain:2Benign:2
- -
- -
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. -

not provided Uncertain:2
Identified in a patient with primary ciliary dyskinesia in published literature, however additional genotype and phenotype information was not provided (Nothe-Menchen et al., 2019); In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; This variant is associated with the following publications: (PMID: 34426522, 35737725, 29402277, 31638833, 37860582) -

not specified Uncertain:1
The p.Leu572Trp variant in DNAH5 has not been previously reported in individuals with primary ciliary dyskinesia, but has been identified in 0.1% (147/120780) o f European chromosomes by the Genome Aggregation Database (gnomAD, http://gnomad .broadinstitute.org; dbSNP rs13787813). Computational prediction tools and conse rvation analysis suggest that the p.Leu572Trp variant may impact the protein, th ough this information is not predictive enough to determine pathogenicity. In su mmary, the clinical significance of the p.Leu572Trp variant is uncertain. ACMG/A MP Criteria applied: PP3. -
