Genes affected

WTIP (HGNC:20964): (WT1 interacting protein) Predicted to enable transcription corepressor activity. Involved in several processes, including negative regulation of hippo signaling; positive regulation of gene silencing by miRNA; and response to hypoxia. Acts upstream of or within gene silencing by miRNA. Located in P-body. [provided by Alliance of Genome Resources, Apr 2022]

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=0.10253325).

The c.185G>A (p.G62E) alteration is located in exon 1 (coding exon 1) of the WTIP gene. This alteration results from a G to A substitution at nucleotide position 185, causing the glycine (G) at amino acid position 62 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
