Genes affected

DUSP22 (HGNC:16077): (dual specificity phosphatase 22) Enables non-membrane spanning protein tyrosine phosphatase activity and protein tyrosine kinase binding activity. Involved in several processes, including cellular response to epidermal growth factor stimulus; negative regulation of focal adhesion assembly; and negative regulation of non-membrane spanning protein tyrosine kinase activity. Acts upstream of or within negative regulation of transcription by RNA polymerase II. Located in plasma membrane. Part of cytoplasm; filamentous actin; and leading edge of lamellipodium.

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.73).
• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.209 is higher than 0.05.
