Genes affected
DNAH9 (HGNC:2953): (dynein axonemal heavy chain 9) This gene encodes the heavy chain subunit of axonemal dynein, a large multi-subunit molecular motor. Axonemal dynein attaches to microtubules and hydrolyzes ATP to mediate the movement of cilia and flagella. The gene expresses at least two transcript variants; additional variants have been described, but their full length nature has not been determined. [provided by RefSeq, Jul 2008]

Significance: Uncertain significance
Review Status: criteria provided, single submitter
Collection Method: clinical testing

The c.42C>G (p.N14K) alteration is located in exon 1 (coding exon 1) of the DNAH9 gene. This alteration results from a C to G substitution at nucleotide position 42, causing the asparagine (N) at amino acid position 14 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
