Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 01, 2023The c.1958C>T (p.A653V) alteration is located in exon 14 (coding exon 14) of the PPP4R3B gene. This alteration results from a C to T substitution at nucleotide position 1958, causing the alanine (A) at amino acid position 653 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
