Genes affected

HIP1 (HGNC:4913): (huntingtin interacting protein 1) The product of this gene is a membrane-associated protein that functions in clathrin-mediated endocytosis and protein trafficking within the cell. The encoded protein binds to the huntingtin protein in the brain; this interaction is lost in Huntington's disease. Alternative splicing results in multiple transcript variants.

The c.2818C>T (p.R940W) alteration is located in exon 28 (coding exon 28) of the HIP1 gene. This alteration results from a C to T substitution at nucleotide position 2818, causing the arginine (R) at amino acid position 940 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
