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.2724T>A (p.H908Q) alteration is located in exon 27 (coding exon 27) of the HIP1 gene. This alteration results from a T to A substitution at nucleotide position 2724, causing the histidine (H) at amino acid position 908 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
