Genes affected

OLIG3 (HGNC:18003): (oligodendrocyte transcription factor 3) Enables sequence-specific double-stranded DNA binding activity. Predicted to be involved in neuron differentiation and regulation of transcription by RNA polymerase II. Predicted to act upstream of or within negative regulation of transcription by RNA polymerase II; spinal cord motor neuron cell fate specification; and spinal cord motor neuron migration. Predicted to be part of chromatin. Predicted to be active in nucleus. [provided by Alliance of Genome Resources, Apr 2022]

Ambry Genetics

Feb 27, 2023

The c.141G>A (p.M47I) alteration is located in exon 1 (coding exon 1) of the OLIG3 gene. This alteration results from a G to A substitution at nucleotide position 141, causing the methionine (M) at amino acid position 47 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
