Genes affected

LUZP4 (HGNC:24971): (leucine zipper protein 4) This gene encodes a leucine-zipper protein that was first defined as a cancer testis antigens. The encoded protein is an RNA binding protein that interacts with the mRNA export receptor nuclear RNA export factor 2. Alternate splicing results in multiple transcript variants.

ACMG classification

Our verdict: Benign. The variant received -9 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.91).
• BP7: Synonymous conserved (PhyloP=-0.909 with no splicing effect.
• BS2: High Hemizygotes in GnomAdExome4 at 2 gene
