Genes affected

CISD1 (HGNC:30880): (CDGSH iron sulfur domain 1) This gene encodes a protein with a CDGSH iron-sulfur domain and has been shown to bind a redox-active [2Fe-2S] cluster. The encoded protein has been localized to the outer membrane of mitochondria and is thought to play a role in regulation of oxidation. Genes encoding similar proteins are located on chromosomes 4 and 17, and a pseudogene of this gene is located on chromosome 2. [provided by RefSeq, Feb 2012]

The c.191A>T (p.D64V) alteration is located in exon 2 (coding exon 2) of the CISD1 gene. This alteration results from a A to T substitution at nucleotide position 191, causing the aspartic acid (D) at amino acid position 64 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
