Genes affected

RTN1 (HGNC:10467): (reticulon 1) This gene belongs to the family of reticulon encoding genes. Reticulons are associated with the endoplasmic reticulum, and are involved in neuroendocrine secretion or in membrane trafficking in neuroendocrine cells. This gene is considered to be a specific marker for neurological diseases and cancer, and is a potential molecular target for therapy. Alternative splicing results in multiple transcript variants.

The c.976G>T (p.D326Y) alteration is located in exon 2 (coding exon 2) of the RTN1 gene. This alteration results from a G to T substitution at nucleotide position 976, causing the aspartic acid (D) at amino acid position 326 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
