Genes affected

MLXIPL (HGNC:12744): (MLX interacting protein like) This gene encodes a basic helix-loop-helix leucine zipper transcription factor of the Myc/Max/Mad superfamily. This protein forms a heterodimeric complex and binds and activates, in a glucose-dependent manner, carbohydrate response element (ChoRE) motifs in the promoters of triglyceride synthesis genes. The gene is deleted in Williams-Beuren syndrome, a multisystem developmental disorder caused by the deletion of contiguous genes at chromosome 7q11.23. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Dec 2015]

The c.1937A>C (p.K646T) alteration is located in exon 12 (coding exon 12) of the MLXIPL gene. This alteration results from a A to C substitution at nucleotide position 1937, causing the lysine (K) at amino acid position 646 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
