Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 04, 2023The c.493C>A (p.L165M) alteration is located in exon 3 (coding exon 3) of the METTL25 gene. This alteration results from a C to A substitution at nucleotide position 493, causing the leucine (L) at amino acid position 165 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
