Ambry Genetics RCV002316087 SCV000847594 uncertain significance Inborn genetic diseases 2016-08-19 criteria provided, single submitter clinical testing The p.R27H variant (also known as c.80G>A), located in coding exon 1 of the GRIN2B gene, results from a G to A substitution at nucleotide position 80. The arginine at codon 27 is replaced by histidine, an amino acid with highly similar properties. This variant was previously reported in the SNPDatabase as rs200727145. This variant was not reported in population based cohorts in the following databases: NHLBI Exome Sequencing Project (ESP) and 1000 Genomes Project. In the ESP, this variant was not observed in 6503 samples (13006 alleles) with coverage at this position. This amino acid position is not well conserved in available vertebrate species. In addition, this alteration is predicted to be benign and tolerated by PolyPhen and SIFT in silico analyses, respectively. Since supporting evidence is limited at this time, the clinical significance of this variant remains unclear.
