Genes affected
TGOLN2 (HGNC:15450): (trans-golgi network protein 2) This gene encodes a type I integral membrane protein that is localized to the trans-Golgi network, a major sorting station for secretory and membrane proteins. The encoded protein cycles between early endosomes and the trans-Golgi network, and may play a role in exocytic vesicle formation. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, Oct 2011]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 01, 2022The c.934G>A (p.V312I) alteration is located in exon 2 (coding exon 2) of the TGOLN2 gene. This alteration results from a G to A substitution at nucleotide position 934, causing the valine (V) at amino acid position 312 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
