Ambry Genetics	RCV002313887	SCV000847626	uncertain significance	Inborn genetic diseases	2017-10-27	criteria provided, single submitter	clinical testing	The p.F183I variant (also known as c.547T>A), located in coding exon 2 of the GRIN2A gene, results from a T to A substitution at nucleotide position 547. The phenylalanine at codon 183 is replaced by isoleucine, an amino acid with highly similar properties. In one study, this variant was detected in an individual with benign epilepsy with centrotemporal spikes (rolandic epilepsy). The variant was not present in the patient's asymptomatic father (mother's variant status unknown) (Lemke JR et al. Nat. Genet., 2013 Sep;45:1067-72). This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be deleterious by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this variant remains unclear.
