Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 01, 2021The c.2407T>A (p.S803T) alteration is located in exon 16 (coding exon 16) of the PPP4R3B gene. This alteration results from a T to A substitution at nucleotide position 2407, causing the serine (S) at amino acid position 803 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
