Genes affected

PHIP (HGNC:15673): (pleckstrin homology domain interacting protein) This gene encodes a protein that binds to the insulin receptor substrate 1 protein and regulates glucose transporter translocation in skeletal muscle cells. The encoded protein may also regulate growth and survival of pancreatic beta cells. Elevated copy number of this gene may be associated with melanoma severity and the encoded protein may promote melanoma metastasis in human patients. [provided by RefSeq, Oct 2016]

IRAK1BP1 (HGNC:17368): (interleukin 1 receptor associated kinase 1 binding protein 1) Predicted to be involved in I-kappaB kinase/NF-kappaB signaling. Predicted to be located in cytoplasm and nucleus. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Our verdict: Pathogenic. The variant received 11 ACMG points.

• PVS1: Loss of function variant, product undergoes nonsense mediated mRNA decay. LoF is a known mechanism of disease.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 6-78961775-G-A is Pathogenic according to our data. Variant chr6-78961775-G-A is described in ClinVar as Pathogenic/Likely_pathogenic. ClinVar VariationId is 545398.Status of the report is no_assertion_criteria_provided, 0 stars.
