Genes affected

KLC3 (HGNC:20717): (kinesin light chain 3) This gene encodes a member of the kinesin light chain gene family. Kinesins are molecular motors involved in the transport of cargo along microtubules, and are composed of two kinesin heavy chain (KHC) and two kinesin light chain (KLC) molecules. KLCs are thought to typically be involved in binding cargo and regulating kinesin activity. In the rat, a protein similar to this gene product is expressed in post-meiotic spermatids, where it associates with structural components of sperm tails and mitochondria.

The c.527C>T (p.S176F) alteration is located in exon 4 (coding exon 3) of the KLC3 gene. This alteration results from a C to T substitution at nucleotide position 527, causing the serine (S) at amino acid position 176 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
