Concept ID:
Disease or Syndrome
Synonyms: Juvenile glaucoma with unusual upper lip and dental roots; MOLAR ROOTS, PYRAMIDAL, WITH JUVENILE GLAUCOMA AND UNUSUAL UPPER LIP; Pyramidal molars, glaucoma, abnormal upper lip
SNOMED CT: Ackerman syndrome (722280000)
Modes of inheritance:
Autosomal recessive inheritance
MedGen UID:
Concept ID:
Intellectual Product
Source: Orphanet
A mode of inheritance that is observed for traits related to a gene encoded on one of the autosomes (i.e., the human chromosomes 1-22) in which a trait manifests in individuals with two pathogenic alleles, either homozygotes (two copies of the same mutant allele) or compound heterozygotes (whereby each copy of a gene has a distinct mutant allele).

Ackerman syndrome has characteristics of pyramidal molar roots and taurodontism associated with variable anomalies. It has been described in two generations of one family. Both parents and their six siblings had pyramidal, taurodont or fused molar roots. Some of the patients also had hypotrichosis, an abnormal upper lip, thickened and wide philtrum, and/or juvenile glaucoma. Other features included entropion of the eyelid, syndactyly and clinodactyly of the fifth fingers. [from SNOMEDCT_US]
