Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 27, 2023The c.797C>T (p.T266M) alteration is located in exon 6 (coding exon 6) of the MPPED2 gene. This alteration results from a C to T substitution at nucleotide position 797, causing the threonine (T) at amino acid position 266 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
