Overview

[edit]

The family with sequence similarity 43 member A (FAM43A) gene codes for a protein that is conserved in primates[1], and orthologs have been found in vertebrate and invertebrate species[2]. Three transcripts have been identified, an un-spliced non-coding transcript ad two protein coding isoforms. [3]

Gene

[edit]

Located on the long arm of Chromosome 3 at 3q29, is comprised of 2,493 bases containing a phosphotyrosine interaction domain, putative phosphoinositide binding site and putative peptide binding sites[4]. Expression at high levels has been recorded in the brain (22), tumor tissue (20), lung (13), spleen (12), pancreas (11), and other tissues[5]. The similar gene in Caenorhabditis elegans XM208, is expressed at a high level (92%) in the embryo and not expressed in the adult; maps to the X-chromosome and the in vivo function is unknown[6]. Global alignment of FAM43A genes of H. sapiens, G. gallus, and C. elegans can be seen below, with G. gallus sharing 72.4% similarity, and C. elegans 35.6%.

Introduction

[edit]

The FAM43A gene has been identified in cDNA screening as a possible cancer development and progression candidate gene[7]. Unpublished data from Zhang et al. indicates that FAM43A could possess tumor suppressor function[8] however the direct interaction is unknown. As well as playing a role in cancer development, FAM43A has been identified as a possible autism spectrum disorder (ASD) candidate gene, with mutations within the upstream SNP rs789859 correlating with the presentation of ASD and learning disorder; suggesting that this SNP is the promoter region for the downstream FAM43A gene[9]. The 2014 study completed by Baron-Cohen et al. involved the screening of 906 K SNPs within the genome to identify possible candidate genes, with FAM43A being the closest gene to the polymorphism.
