Variant summary
Our verdict is Likely benign. Variant got -5 ACMG points: 0P and 5B. BP6BS1
The NM_001369.3(DNAH5):c.975+6C>T variant causes a splice region, intron change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000333 in 1,613,900 control chromosomes in the GnomAD database, including 2 homozygotes. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars).

Primary ciliary dyskinesia 3 Uncertain:2
The DNAH5 c.975+6C>T variant (rs151000177) is reported in an individual with bronchiectasis who carried an additional variant in DNAH5; both variants were classified as uncertain significance (Guan 2018). The c.975+6C>T variant is also reported in ClinVar (Variation ID: 414355). It is observed in the general population with an overall allele frequency of 0.05% (151/282240 alleles) in the Genome Aggregation Database. Computational analyses are conflicting in whether this variant is predicted to alter splicing (Alamut Visual Plus v.1.5.1, SpliceAI). Due to limited information, the clinical significance of this variant is uncertain at this time. References: Guan WJ et al.

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. -
