Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 24, 2024The c.10G>T (p.A4S) alteration is located in exon 1 (coding exon 1) of the METTL17 gene. This alteration results from a G to T substitution at nucleotide position 10, causing the alanine (A) at amino acid position 4 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
