Genes affected

NIPSNAP2 (HGNC:4179): (nipsnap homolog 2) This gene encodes a member of the NipSnap family of proteins that may be involved in vesicular transport. The encoded protein is localized to mitochondria and plays a role in oxidative phosphorylation. A pseudogene of this gene is located on the long arm of chromosome 2. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, Feb 2011]

The c.389A>G (p.Y130C) alteration is located in exon 5 (coding exon 5) of the GBAS gene. This alteration results from a A to G substitution at nucleotide position 389, causing the tyrosine (Y) at amino acid position 130 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
