Genes affected

AMBN (HGNC:452): (ameloblastin) This gene encodes the nonamelogenin enamel matrix protein ameloblastin. The encoded protein may be important in enamel matrix formation and mineralization. This gene is located in the calcium-binding phosphoprotein gene cluster on chromosome 4. Mutations in this gene may be associated with dentinogenesis imperfect and autosomal dominant amylogenesis imperfect. [provided by RefSeq, Aug 2011]

Ambry Genetics

Feb 22, 2023

The c.202G>A (p.G68R) alteration is located in exon 5 (coding exon 5) of the AMBN gene. This alteration results from a G to A substitution at nucleotide position 202, causing the glycine (G) at amino acid position 68 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
