Genes affected

TM2D2 (HGNC:24127): (TM2 domain containing 2) 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. This gene has multiple alternatively spliced transcript variants which encode two different isoforms.

The c.148G>T (p.A50S) alteration is located in exon 1 (coding exon 1) of the TM2D2 gene. This alteration results from a G to T substitution at nucleotide position 148, causing the alanine (A) at amino acid position 50 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
