Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 09, 2024The c.386G>A (p.R129K) alteration is located in exon 4 (coding exon 3) of the METTL6 gene. This alteration results from a G to A substitution at nucleotide position 386, causing the arginine (R) at amino acid position 129 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
