Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 31, 2024The c.2640G>A (p.M880I) alteration is located in exon 18 (coding exon 18) of the RGS22 gene. This alteration results from a G to A substitution at nucleotide position 2640, causing the methionine (M) at amino acid position 880 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
