Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 19, 2023The c.937T>G (p.S313A) alteration is located in exon 7 (coding exon 7) of the PPM1M gene. This alteration results from a T to G substitution at nucleotide position 937, causing the serine (S) at amino acid position 313 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
