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 is predicted to replace isoleucine with methionine at codon 642 of the APPL1 protein (p.(Ile642Met)). The isoleucine residue is weakly conserved (100 vertebrates, UCSC), and is a small physicochemical difference between isoleucine and methionine. The variant is present in the East Asian population at a frequency of 0.4% (rs183787750, 72/18,994 alleles in gnomAD v2.1), and has not been reported in the relevant medical literature or databases. Multiple lines of computational evidence predict a benign effect for the missense substitution (6/6 algorithms). Based on the classification scheme RMH Modified ACMG Guidelines v1.3.1, this variant is classified as Likely benign. Following criteria are met: BS1, BP4. -
