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. [provided by RefSeq, Oct 2009]

The c.551A>G (p.Y184C) alteration is located in exon 6 (coding exon 6) of the TRAM1 gene. This alteration results from a A to G substitution at nucleotide position 551, causing the tyrosine (Y) at amino acid position 184 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
