Genes affected

MLX (HGNC:11645): (MAX dimerization protein MLX) The product of this gene belongs to the family of basic helix-loop-helix leucine zipper (bHLH-Zip) transcription factors. These factors form heterodimers with Mad proteins and play a role in proliferation, determination and differentiation. This gene product may act to diversify Mad family function by its restricted association with a subset of the Mad family of transcriptional repressors, namely, Mad1 and Mad4. Alternatively spliced transcript variants encoding different isoforms have been identified for this gene. [provided by RefSeq, Jul 2008]

The c.133T>C (p.S45P) alteration is located in exon 1 (coding exon 1) of the MLX gene. This alteration results from a T to C substitution at nucleotide position 133, causing the serine (S) at amino acid position 45 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
