Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 07, 2023The c.1496C>T (p.T499M) alteration is located in exon 3 (coding exon 2) of the PLEKHM3 gene. This alteration results from a C to T substitution at nucleotide position 1496, causing the threonine (T) at amino acid position 499 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
