Genes affected

HOMER2 (HGNC:17513): (homer scaffold protein 2) This gene encodes a member of the homer family of dendritic proteins. Members of this family regulate group 1 metabotrophic glutamate receptor function. The encoded protein is a postsynaptic density scaffolding protein. Alternative splicing results in multiple transcript variants. Two related pseudogenes have been identified on chromosome 14. [provided by RefSeq, Jun 2011]

The c.1034G>A (p.R345Q) alteration is located in exon 9 (coding exon 9) of the HOMER2 gene. This alteration results from a G to A substitution at nucleotide position 1034, causing the arginine (R) at amino acid position 345 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
