Genes affected
RSC1A1 (HGNC:10458): (regulator of solute carriers 1) The protein encoded by this intronless gene inhibits the expression of the solute carrier family 5 (sodium/glucose cotransporter), member 1 gene (SLC5A1) and downregulates exocytosis of the SLC5A1 protein. The encoded protein is sometimes found coating the trans-Golgi network and other times is localized to the nucleus, depending on the cell cycle stage. This protein also inhibits the expression of solute carrier family 22 (organic cation transporter), member 2 (SLC22A2). [provided by RefSeq, Dec 2015]
DDI2 (HGNC:24578): (DNA damage inducible 1 homolog 2) Enables aspartic-type endopeptidase activity; identical protein binding activity; and ubiquitin binding activity. Involved in several processes, including cellular response to hydroxyurea; proteolysis; and regulation of DNA stability. Located in cytosol and nucleoplasm.

The c.34C>T (p.H12Y) alteration is located in exon 1 (coding exon 1) of the RSC1A1 gene. This alteration results from a C to T substitution at nucleotide position 34, causing the histidine (H) at amino acid position 12 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
