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]

PHIP-related disorder Pathogenic:1
Likely pathogenic, no assertion criteria providedclinical testingPreventionGenetics, part of Exact SciencesMay 23, 2024The PHIP c.2902C>T variant is predicted to result in premature protein termination (p.Arg968*). This variant was reported in two unrelated individuals with developmental delay, obesity, and dysmorphism; and in at least one case, this variant was observed de novo (Jansen et al. 2018. PubMed ID: 29209020; Kaur et al. 2021. PubMed ID: 33867250). This variant is reported in 0.0018% of alleles in individuals of European (Non-Finnish) descent in gnomAD. Nonsense variants in PHIP are expected to be pathogenic. This variant is interpreted as likely pathogenic. -
