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]

The c.909C>G (p.I303M) alteration is located in exon 10 (coding exon 10) of the HOOK3 gene. This alteration results from a C to G substitution at nucleotide position 909, causing the isoleucine (I) at amino acid position 303 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
