Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 15, 2023The c.2555A>G (p.K852R) alteration is located in exon 17 (coding exon 17) of the RGS22 gene. This alteration results from a A to G substitution at nucleotide position 2555, causing the lysine (K) at amino acid position 852 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
