Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 04, 2022The c.1597A>G (p.I533V) alteration is located in exon 11 (coding exon 11) of the PPP4R3B gene. This alteration results from a A to G substitution at nucleotide position 1597, causing the isoleucine (I) at amino acid position 533 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
