Description

The c.2214G>C (p.K738N) alteration is located in exon 14 (coding exon 13) of the GRIA4 gene. This alteration results from a G to C substitution at nucleotide position 2214, causing the lysine (K) at amino acid position 738 to be replaced by an asparagine (N). Based on data from gnomAD, the C allele has an overall frequency of <0.001% (1/250746) total alleles studied. This amino acid position is highly conserved in available vertebrate species. This alteration is predicted to be tolerated by in silico analysis. Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear.
