Genes affected

MSC (HGNC:7321): (musculin) The protein encoded by this gene is a transcriptional repressor capable of binding an E-box element either as a homodimer or as a heterodimer with E2A in vitro. The encoded protein also forms heterodimers with E2A proteins in vivo. This protein is capable of inhibiting the transactivation capability of E47, an E2A protein, in mammalian cells. This gene is a downstream target of the B-cell receptor signal transduction pathway. [provided by RefSeq, Jul 2008]

The c.241G>A (p.G81S) alteration is located in exon 1 (coding exon 1) of the MSC gene. This alteration results from a G to A substitution at nucleotide position 241, causing the glycine (G) at amino acid position 81 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
