Genes affected

TM2D3 (HGNC:24128): (TM2 domain containing 3) The protein encoded by this gene contains a structural module related to that of the seven transmembrane domain G protein-coupled receptor superfamily. This protein has sequence and structural similarities to the beta-amyloid binding protein (BBP), but, unlike BBP, it does not regulate a response to beta-amyloid peptide. This protein may have regulatory roles in cell death or proliferation signal cascades. Several alternatively spliced transcript variants of this gene are described but the full length nature of some variants has not been determined. Multiple polyadenylation sites have been found in this gene. [provided by RefSeq, Jul 2008]

The c.434T>C (p.M145T) alteration is located in exon 4 (coding exon 4) of the TM2D3 gene. This alteration results from a T to C substitution at nucleotide position 434, causing the methionine (M) at amino acid position 145 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
