Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 28, 2024The c.1097T>C (p.L366P) alteration is located in exon 9 (coding exon 9) of the PPM1M gene. This alteration results from a T to C substitution at nucleotide position 1097, causing the leucine (L) at amino acid position 366 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
