Genes affected

PDE7A (HGNC:8791): (phosphodiesterase 7A) The protein encoded by this gene belongs to the cyclic nucleotide phosphodiesterase (PDE) family, and PDE7 subfamily. This PDE hydrolyzes the second messenger, cAMP, which is a regulator and mediator of a number of cellular responses to extracellular signals. Thus, by regulating the cellular concentration of cAMP, this protein plays a key role in many important physiological processes. Alternatively spliced transcript variants encoding different isoforms have been described for this gene. [provided by RefSeq, Jul 2011]

PDE7A links:

MTFR1 (HGNC:29510): (mitochondrial fission regulator 1) This gene encodes a mitochondrial protein that is characterized by a poly-proline rich region. A chicken homolog of this protein promotes mitochondrial fission and the mouse homolog protects cells from oxidative stress. A related pseudogene of this gene is found on chromosome X.

The c.469G>C (p.D157H) alteration is located in exon 1 (coding exon 1) of the PDE7A gene. This alteration results from a G to C substitution at nucleotide position 469, causing the aspartic acid (D) at amino acid position 157 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
