Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 26, 2024The c.290G>A (p.R97H) alteration is located in exon 5 (coding exon 5) of the PPP3R1 gene. This alteration results from a G to A substitution at nucleotide position 290, causing the arginine (R) at amino acid position 97 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
