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 3 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.757

The c.638G>T (p.C213F) alteration is located in exon 9 (coding exon 9) of the LUZP2 gene. This alteration results from a G to T substitution at nucleotide position 638, causing the cysteine (C) at amino acid position 213 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
