Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 21, 2022The c.679G>A (p.G227R) alteration is located in exon 6 (coding exon 4) of the METTL15 gene. This alteration results from a G to A substitution at nucleotide position 679, causing the glycine (G) at amino acid position 227 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
