Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 11, 2024The c.236T>A (p.V79E) alteration is located in exon 3 (coding exon 2) of the METTL21A gene. This alteration results from a T to A substitution at nucleotide position 236, causing the valine (V) at amino acid position 79 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
