Genes affected

DNALI1 (HGNC:14353): (dynein axonemal light intermediate chain 1) This gene is the human homolog of the Chlamydomonas inner dynein arm gene, p28. The precise function of this gene is not known, however, it is a potential candidate for immotile cilia syndrome (ICS). Ultrastructural defects of the inner dynein arms are seen in patients with ICS. Immotile mutant strains of Chlamydomonas, a biflagellated algae, exhibit similar defects. [provided by RefSeq, Jul 2008]

Collection Method: clinical testing

The c.497C>T (p.A166V) alteration is located in exon 4 (coding exon 4) of the DNALI1 gene. This alteration results from a C to T substitution at nucleotide position 497, causing the alanine (A) at amino acid position 166 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
