Genes affected

SLC35C2 (HGNC:17117): (solute carrier family 35 member C2) This gene encodes a member of the triose-phosphate transporter protein family. This gene is regulated by oxygen tension, is induced in hypoxic trophoblast cells, and is overexpressed in ovarian cancer. Alternative splicing results in multiple transcript variants. A pseudogene of this gene has been defined on the X chromosome. [provided by RefSeq, Jul 2013]

The c.413C>T (p.A138V) alteration is located in exon 6 (coding exon 5) of the SLC35C2 gene. This alteration results from a C to T substitution at nucleotide position 413, causing the alanine (A) at amino acid position 138 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
