Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 30, 2024The c.519T>A (p.H173Q) alteration is located in exon 3 (coding exon 3) of the METTL21B gene. This alteration results from a T to A substitution at nucleotide position 519, causing the histidine (H) at amino acid position 173 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
