Genes affected

GOLM1 (HGNC:15451): (golgi membrane protein 1) The Golgi complex plays a key role in the sorting and modification of proteins exported from the endoplasmic reticulum. The protein encoded by this gene is a type II Golgi transmembrane protein. It processes proteins synthesized in the rough endoplasmic reticulum and assists in the transport of protein cargo through the Golgi apparatus. The expression of this gene has been observed to be upregulated in response to viral infection. Alternatively spliced transcript variants encoding the same protein have been described for this gene.

The c.580A>G (p.N194D) alteration is located in exon 6 (coding exon 5) of the GOLM1 gene. This alteration results from a A to G substitution at nucleotide position 580, causing the asparagine (N) at amino acid position 194 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
