Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 22, 2023The c.301G>T (p.A101S) alteration is located in exon 1 (coding exon 1) of the ALKBH5 gene. This alteration results from a G to T substitution at nucleotide position 301, causing the alanine (A) at amino acid position 101 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
