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 Pathogenic. Variant got 11 ACMG points.

• PVS1: Splicing +-2 bp (donor or acceptor) variant, LoF is a know mechanism of disease, No cryptic splice site detected. Exon removal results in frameshift change.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 11-65348932-G-A is Pathogenic according to our data. Variant chr11-65348932-G-A is described in ClinVar as [Pathogenic]. Clinvar id is 545686.Status of the report is no_assertion_criteria_provided, 0 stars. Variant chr11-65348932-G-A is described in Lovd as [Pathogenic].
