not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 22, 2024The c.1291C>G (p.P431A) alteration is located in exon 10 (coding exon 9) of the METTL16 gene. This alteration results from a C to G substitution at nucleotide position 1291, causing the proline (P) at amino acid position 431 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
