Genes affected

HOOK2 (HGNC:19885): (hook microtubule tethering protein 2) 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]

Oct 28, 2024

The c.2119C>T (p.R707C) alteration is located in exon 23 (coding exon 23) of the HOOK2 gene. This alteration results from a C to T substitution at nucleotide position 2119, causing the arginine (R) at amino acid position 707 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
