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]

Jan 23, 2024

The c.601G>T (p.A201S) alteration is located in exon 1 (coding exon 1) of the OLIG3 gene. This alteration results from a G to T substitution at nucleotide position 601, causing the alanine (A) at amino acid position 201 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
