Genes affected

HOOK3 (HGNC:23576): (hook microtubule tethering protein 3) Hook proteins are cytosolic coiled-coil proteins that contain conserved N-terminal domains, which attach to microtubules, and more divergent C-terminal domains, which mediate binding to organelles. The Drosophila Hook protein is a component of the endocytic compartment.[supplied by OMIM, Apr 2004]

Collection Method: clinical testing

The c.409C>G (p.Q137E) alteration is located in exon 6 (coding exon 6) of the HOOK3 gene. This alteration results from a C to G substitution at nucleotide position 409, causing the glutamine (Q) at amino acid position 137 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
