Genes affected
ENAM (HGNC:3344): (enamelin) Dental enamel forms the outer cap of teeth and is the hardest substance found in vertebrates. This gene encodes the largest protein in the enamel matrix of developing teeth. The protein is involved in the mineralization and structural organization of enamel. Defects in this gene result in amelogenesis imperfect type 1C.[provided by RefSeq, Oct 2009]

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 06, 2023The c.214G>A (p.A72T) alteration is located in exon 6 (coding exon 5) of the ENAM gene. This alteration results from a G to A substitution at nucleotide position 214, causing the alanine (A) at amino acid position 72 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
