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]
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.

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 24, 2022The c.790G>A (p.V264M) alteration is located in exon 9 (coding exon 9) of the TRAM2 gene. This alteration results from a G to A substitution at nucleotide position 790, causing the valine (V) at amino acid position 264 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
