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.

• PM1: In a zinc_finger_region PHD-type 2 (size 50) in uniprot entity REQU_HUMAN there are 6 pathogenic changes around while only 0 benign (100%) in NM_006268.5
• 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.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.949
• PP5: Variant 11-65348869-A-G is Pathogenic according to our data. Variant chr11-65348869-A-G is described in ClinVar as [Pathogenic]. Clinvar id is 545685.Status of the report is criteria_provided_single_submitter, 1 stars. Variant chr11-65348869-A-G is described in Lovd as [Likely_pathogenic].
