not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 15, 2023The c.4847G>A (p.R1616Q) alteration is located in exon 17 (coding exon 17) of the QRICH2 gene. This alteration results from a G to A substitution at nucleotide position 4847, causing the arginine (R) at amino acid position 1616 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
