Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 18, 2023The c.1340C>T (p.P447L) alteration is located in exon 10 (coding exon 9) of the METTL16 gene. This alteration results from a C to T substitution at nucleotide position 1340, causing the proline (P) at amino acid position 447 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
