Genes affected

RBM12 (HGNC:9898): (RNA binding motif protein 12) This gene encodes a protein that contains several RNA-binding motifs, potential transmembrane domains, and proline-rich regions. This gene and the gene for copine I overlap at map location 20q11.21. Alternative splicing in the 5' UTR results in four transcript variants. All variants encode the same protein. [provided by RefSeq, Nov 2010]

RBM12 links:

CPNE1 (HGNC:2314): (copine 1) Calcium-dependent membrane-binding proteins may regulate molecular events at the interface of the cell membrane and cytoplasm. This gene encodes a calcium-dependent protein that also contains two N-terminal type II C2 domains and an integrin A domain-like sequence in the C-terminus. However, the encoded protein does not contain a predicted signal sequence or transmembrane domains. This protein has a broad tissue distribution and it may function in membrane trafficking. This gene and the gene for RNA binding motif protein 12 overlap at map location 20q11.21. Alternate splicing results in multiple transcript variants encoding different proteins.

Ambry Genetics

Dec 22, 2023

The c.2024C>T (p.T675I) alteration is located in exon 3 (coding exon 1) of the RBM12 gene. This alteration results from a C to T substitution at nucleotide position 2024, causing the threonine (T) at amino acid position 675 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
