Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 08, 2021The c.11T>G (p.V4G) alteration is located in exon 2 (coding exon 1) of the METTL21A gene. This alteration results from a T to G substitution at nucleotide position 11, causing the valine (V) at amino acid position 4 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
