Genes affected
NGB (HGNC:14077): (neuroglobin) This gene encodes an oxygen-binding protein that is distantly related to members of the globin gene family. It is highly conserved among other vertebrates. It is expressed in the central and peripheral nervous system where it may be involved in increasing oxygen availability and providing protection under hypoxic/ischemic conditions.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 22, 2022The c.58C>G (p.P20A) alteration is located in exon 1 (coding exon 1) of the NGB gene. This alteration results from a C to G substitution at nucleotide position 58, causing the proline (P) at amino acid position 20 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
