Genes affected

HYDIN (HGNC:19368): (HYDIN axonemal central pair apparatus protein) This gene encodes a protein that may be involved in cilia motility. Mutations in this gene cause of autosomal recessive primary ciliary dyskinesia-5, a disorder characterized by the accumulation of cerebrospinal fluid within the ventricles of the brain. A duplicate copy of this gene has been found in humans on chromosome 1. [provided by RefSeq, Jan 2013]

The c.14504T>A (p.I4835N) alteration is located in exon 84 (coding exon 83) of the HYDIN gene. This alteration results from a T to A substitution at nucleotide position 14504, causing the isoleucine (I) at amino acid position 4835 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
