Genes affected

TMEM208 (HGNC:25015): (transmembrane protein 208) This gene encodes a highly conserved protein which is localized in the endoplasmic reticulum (ER). The protein is linked to autophagy and ER stress. Knockdown of this gene increased autophagy and triggered ER stress. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Dec 2015]

The c.293T>C (p.M98T) alteration is located in exon 4 (coding exon 4) of the TMEM208 gene. This alteration results from a T to C substitution at nucleotide position 293, causing the methionine (M) at amino acid position 98 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
