Genes affected

MLXIP (HGNC:17055): (MLX interacting protein) This gene encodes a protein that functions as part of a heterodimer to activate transcription. The encoded protein forms a heterodimer with Max-like protein X (MLX) and is involved in the regulation of genes in response to cellular glucose levels. [provided by RefSeq, Mar 2014]

MLXIP (HGNC:):

ACMG classification

Verdict is Uncertain_significance. Variant got 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.19027105).

The c.1315C>T (p.P439S) alteration is located in exon 8 (coding exon 8) of the MLXIP gene. This alteration results from a C to T substitution at nucleotide position 1315, causing the proline (P) at amino acid position 439 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
