Primary ciliary dyskinesia 7 Uncertain:2
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 DNAH11 c.727A>G; p.Ile243Val variant (rs189000268; ClinVar Variation ID: 696975) is reported in the literature in multiple individuals affected with congenital heart disease/heterotaxy syndrome or otherwise suspected of a primary ciliary dyskinesia (Liu 2019 and Guan 2021). This variant is found in the East Asian population with an allele frequency of 0.36% 67/19392 alleles) in the Genome Aggregation Database (v2.1.1). Computational analyses predict that this variant is neutral (REVEL: 0.071). However, given the lack of clinical and functional data, the significance of this variant is uncertain at this time.

Primary ciliary dyskinesia Benign: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. -
