Genes affected

DPF2 (HGNC:9964): (double PHD fingers 2) The protein encoded by this gene is a member of the d4 domain family, characterized by a zinc finger-like structural motif. This protein functions as a transcription factor which is necessary for the apoptotic response following deprivation of survival factors. It likely serves a regulatory role in rapid hematopoietic cell growth and turnover. This gene is considered a candidate gene for multiple endocrine neoplasia type I, an inherited cancer syndrome involving multiple parathyroid, enteropancreatic, and pituitary tumors.

ACMG classification

Verdict is Uncertain_significance. Variant got 3 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant in gene, where missense usually causes diseases (based on misZ statistic), DPF2. . Gene score misZ 2.8982 (greater than the threshold 3.09). Trascript score misZ 3.3532 (greater than threshold 3.09). GenCC has associacion of gene with Coffin-Siris syndrome 7, Coffin-Siris syndrome.

This sequence change replaces glutamine, which is neutral and polar, with leucine, which is neutral and non-polar, at codon 23 of the DPF2 protein (p.Gln23Leu). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with DPF2-related conditions. An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
