Genes affected

GIGYF2 (HGNC:11960): (GRB10 interacting GYF protein 2) This gene contains CAG trinucleotide repeats and encodes a protein containing several stretches of polyglutamine residues. The encoded protein may be involved in the regulation of tyrosine kinase receptor signaling. This gene is located in a chromosomal region that was genetically linked to Parkinson disease type 11, and mutations in this gene were thought to be causative for this disease. However, more recent studies in different populations have been unable to replicate this association. Alternative splicing results in multiple transcript variants. [provided by RefSeq, May 2013]

Collection Method: clinical testing

The c.110A>G (p.K37R) alteration is located in exon 4 (coding exon 2) of the GIGYF2 gene. This alteration results from a A to G substitution at nucleotide position 110, causing the lysine (K) at amino acid position 37 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
