Genes affected

SLC25A17 (HGNC:10987): (solute carrier family 25 member 17) This gene encodes a peroxisomal membrane protein that belongs to the family of mitochondrial solute carriers. It is expressed in the liver, and is likely involved in transport. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Sep 2013]

The c.814G>A (p.A272T) alteration is located in exon 9 (coding exon 9) of the SLC25A17 gene. This alteration results from a G to A substitution at nucleotide position 814, causing the alanine (A) at amino acid position 272 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
