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]

APPL1 links:

ASB14 (HGNC:19766): (ankyrin repeat and SOCS box containing 14) The protein encoded by this gene is a member of the ankyrin repeat and SOCS box-containing (ASB) family of proteins. They contain ankyrin repeat sequence and a SOCS box domain. The SOCS box serves to couple suppressor of cytokine signalling (SOCS) proteins and their binding partners with the elongin B and C complex, possibly targeting them for degradation. Alternative splicing results in multiple transcript variants encoding different isoforms.[provided by RefSeq, Dec 2008]

This sequence change replaces lysine, which is basic and polar, with arginine, which is basic and polar, at codon 704 of the APPL1 protein (p.Lys704Arg). This variant is present in population databases (rs142166154, gnomAD 0.02%). This variant has not been reported in the literature in individuals affected with APPL1-related conditions. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
