Genes affected

APPL1 (HGNC:24035): (adaptor protein, phosphotyrosine interacting with PH domain and leucine zipper 1) The protein encoded by this gene has been shown to be involved in the regulation of cell proliferation, and in the crosstalk between the adiponectin signalling and insulin signalling pathways. The encoded protein binds many other proteins, including RAB5A, DCC, AKT2, PIK3CA, adiponectin receptors, and proteins of the NuRD/MeCP1 complex. This protein is found associated with endosomal membranes, but can be released by EGF and translocated to the nucleus. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Pathogenic. Variant got 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 3-57260016-T-A is Pathogenic according to our data. Variant chr3-57260016-T-A is described in ClinVar as [Pathogenic]. Clinvar id is 208074.Status of the report is no_assertion_criteria_provided, 0 stars.
