Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 26, 2024The c.2389C>T (p.P797S) alteration is located in exon 16 (coding exon 16) of the PPP4R3B gene. This alteration results from a C to T substitution at nucleotide position 2389, causing the proline (P) at amino acid position 797 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
