Genes affected

TRAM2 (HGNC:16855): (translocation associated membrane protein 2) TRAM2 is a component of the translocon, a gated macromolecular channel that controls the posttranslational processing of nascent secretory and membrane proteins at the endoplasmic reticulum (ER) membrane.[supplied by OMIM, Jul 2004]

TRAM2 links:

EFHC1 (HGNC:16406): (EF-hand domain containing 1) This gene encodes an EF-hand-containing calcium binding protein. The encoded protein likely plays a role in calcium homeostasis. Mutations in this gene have been associated with susceptibility to juvenile myoclonic epilepsy and juvenile absence epilepsy. Alternatively spliced transcript variants have been described.

Ambry Genetics

Jul 23, 2024

The c.569G>A (p.R190H) alteration is located in exon 7 (coding exon 7) of the TRAM2 gene. This alteration results from a G to A substitution at nucleotide position 569, causing the arginine (R) at amino acid position 190 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
