Genes affected
ODAPH (HGNC:26300): (odontogenesis associated phosphoprotein) Dental enamel forms the outer cap of teeth and is the hardest substance found in vertebrates. This gene is thought to encode an extracellular matrix acidic phosphoprotein that has a function in enamel mineralization during amelogenesis. Mutations in this gene are associated with recessive hypomineralized amelogenesis imperfecta. [provided by RefSeq, Oct 2012]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 01, 2021The c.236C>T (p.S79L) alteration is located in exon 3 (coding exon 3) of the C4orf26 gene. This alteration results from a C to T substitution at nucleotide position 236, causing the serine (S) at amino acid position 79 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
