Malformative syndrome

A malformative syndrome (or malformation syndrome) is a recognizable pattern of congenital anomalies that are known or thought to be causally related (VIIth International Congress on Human Genetics).

Causes

  • exogenous causes
    • exogenous toxic (teratogenetic agents)
    • ionizing radiations
    • fetal infections (maternofetal infections)
  • genetic causes (or intrinsic causes) (genetic malformative diseases)
    • chromosomal anomalies (chromosomal malformative diseases)
    • numerical chromosomal anomalies (e.g. trisomy 13, trisomy 18, trisomy 21)
    • structural chromosomal anomalies
      • microdeletions (microdeletion syndromes)
      • chromosomal rearrangements
  • gene mutations (monogenic malformative diseases)
    • Kabuki mask syndrome: MLL2
    • Joubert syndrome, Meckel syndrome and related syndromes: TMEM216
    • cleft lip with and without cleft palate: MAFB and ABCA4
    • Schinzel–Giedion syndrome: SETBP1
    • Fanconi anemia and related disorders: RAD51C
    • Noonan syndrome: NRAS
    • generalized lymph vessel dysplasia: CCBE1
    • brachydactyly-anonychia: SOX9
    • genetic metabolic diseases
