Genes affected

TRAM1 (HGNC:20568): (translocation associated membrane protein 1) This gene encodes a multi-pass membrane protein that is part of the mammalian endoplasmic reticulum. The encoded protein influences glycosylation and facilitates the translocation of secretory proteins across the endoplasmic reticulum membrane by regulating which domains of the nascent polypeptide chain are visible to the cytosol during a translocational pause.

Collection Method:clinical testing

The c.899T>C (p.V300A) alteration is located in exon 10 (coding exon 10) of the TRAM1 gene. This alteration results from a T to C substitution at nucleotide position 899, causing the valine (V) at amino acid position 300 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
