Submissions by phenotype
Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | May 18, 2022 | The c.719G>A (p.R240Q) alteration is located in exon 2 (coding exon 1) of the PRRT2 gene. This alteration results from a G to A substitution at nucleotide position 719, causing the arginine (R) at amino acid position 240 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
