Primary ciliary dyskinesia Uncertain:2Benign:1
The p.T4483M variant (also known as c.13448C>T), located in coding exon 77 of the DNAH5 gene, results from a C to T substitution at nucleotide position 13448. The threonine at codon 4483 is replaced by methionine, an amino acid with similar properties. This variant was previously reported in the SNPDatabase as rs141828476. Based on data from the NHLBI Exome Sequencing Project (ESP), the T allele has an overall frequency of approximately 0.02% (2/13006) total alleles studied, having been observed in 0.05% (2/4406) African American alleles. This amino acid position is highly conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this variant remains unclear. -

Primary ciliary dyskinesia 3 Uncertain:1
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. -
