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.307G>A (p.V103M) alteration is located in exon 5 (coding exon 5) of the HOOK3 gene. This alteration results from a G to A substitution at nucleotide position 307, causing the valine (V) at amino acid position 103 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
