Genes affected

LUZP2 (HGNC:23206): (leucine zipper protein 2) This gene encodes a leucine zipper protein. This protein is deleted in some patients with Wilms tumor-Aniridia-Genitourinary anomalies-mental Retardation (WAGR) syndrome. Alternate splicing results in multiple transcript variants. [provided by RefSeq, Oct 2011]

ACMG classification

Verdict is Uncertain_significance. Variant got 1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.33965474).

The c.623A>T (p.E208V) alteration is located in exon 9 (coding exon 9) of the LUZP2 gene. This alteration results from a A to T substitution at nucleotide position 623, causing the glutamic acid (E) at amino acid position 208 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
