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.

Dec 30, 2023

The c.34C>T (p.L12F) alteration is located in exon 1 (coding exon 1) of the TM2D2 gene. This alteration results from a C to T substitution at nucleotide position 34, causing the leucine (L) at amino acid position 12 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
