Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 19, 2024The c.52G>C (p.D18H) alteration is located in exon 1 (coding exon 1) of the METTL11B gene. This alteration results from a G to C substitution at nucleotide position 52, causing the aspartic acid (D) at amino acid position 18 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
