All identified genetic variants were numbered based on cDNA reference sequences and as recommended by the Human Genome Variation Society (http://www.hgvs.org/mutnomen). RefSeq accession numbers for the sequences used in the analyses were as follows: NM_017950.3 (CCDC40), NM_012144.2 (DNAI1), NM_001369.2 (DNAH5), NM_031427.3 (DNAL1), NM_001277115.1 (DNAH11), NM_012472.3 (LRRC6), NM_024532.4 (SPAG16), and NM_206996.2 (SPAG17).
a According to VarSome (1000 Genome Project, ExaC)
b ACMG: American College of Medical Genetics and Genomics.
c Deleterious annotation of genetic variants using neural networks (DANN). The value range is from 0 to 1, with 1 given to the variants predicted to be the most damaging.
d SIFT (sorts intolerant from tolerant) is an in silico prediction tool based on sequence homology derived from closely related sequences collected through PSI-BLAST. Provean (Protein Variation Effect Analyzer) is an in silico tool that predicts how nonsynonymous or in-frame indel variant will affect a protein's biological function.
e This variant does not have automated ACMG/AMP 2015 interpretation
