Genes affected

GIT1 (HGNC:4272): (GIT ArfGAP 1) Enables gamma-tubulin binding activity. Involved in positive regulation of microtubule nucleation and regulation of cytokinesis. Located in several cellular components, including focal adhesion; microtubule cytoskeleton; and mitochondrion. Implicated in attention deficit hyperactivity disorder. Biomarker of Huntington's disease. [provided by Alliance of Genome Resources, Apr 2022]

The c.1735T>G (p.S579A) alteration is located in exon 17 (coding exon 17) of the GIT1 gene. This alteration results from a T to G substitution at nucleotide position 1735, causing the serine (S) at amino acid position 579 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
