Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 09, 2021The c.265C>A (p.H89N) alteration is located in exon 1 (coding exon 1) of the OLIG1 gene. This alteration results from a C to A substitution at nucleotide position 265, causing the histidine (H) at amino acid position 89 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
