  • Fryns J P, Kleczkowska A, Decock P, Massa G, Van den Berghe H: 46,XX/46,XX,del(20)(pter to p12.2) mosaicism limited to fibroblasts associated with MCA/MR and severe growth deficit. Ann. Genet. 35:234-236, 1992. [PubMed: 1296522]
    Patient K.L. was 8 years old.
    mos46,XX(13)/46,XX,del(20)(p12.2)(7)-skin.
    Patient had normal blood chromosomes. No obligatory signs of Alagille-Watson syndrome were present except the dysmorphic features.
    Aberration: Terminal deletion
    Chromosomal Aneuploidy: 20p-

    Patient was 16 years old; mother''s and sib''s karyotypes were normal.
    46,XY,del(20)(p12.2).
    Aberration: Terminal deletion
    Negative band
  • Robert M L P, Lopez T, Crolla J, Huang S, Owen C, Burvill-Homes L, Stumper O, Turnpenny P D.: Alagille syndrome with deletion 20p12.2-p12.3 and hypoplastic left heart. Clin. Dysmorphol. 16: 241-246, 2007. [PubMed: 17786115]
    46,XY,del(20)(p12.2p13).
    The 5 year old had significant learning difficulties, delayed growth and Norwood heart procedures.
    Aberration: Interstitial deletion
    Chromosomal Aneuploidy: 20p-
    Index Terms: Alagille syndrome,Hypoplastic left heart.
  • Sauter S, von Beust G, Burfeind P, Weise A, Starke H, Liehr T, Zoll B.: Autistic disorder and chromosomal mosaicism 46,XY[123]/46,XY,del(20)(pter->p12.2)[10]. AJMG 120A:533-536, 2003. [PubMed: 12884434]
    Blood=46,XY[123]/46,XY,del(20)(pter->p12.2)[10].
    The patient (F) was 3 7/12 year old boy suffering from motor developmental delay and MR.
    Aberration: Terminal deletion
    Chromosomal Aneuploidy: 20p-
    Index Terms: Autis(tic)
  • Stankiewicz P, Rujner J, Loffler C, Kruger A, Nimmakayalu M, Pilacik B, Krajewska-Walasek M, Gutkowska A, Hansmann I, Giannakudis I.: Alagille syndrome associated with a paracentric inversion 20p12.2p13 disrupting the JAG1 gene. AJMG 103:166-171, 2001. [PubMed: 11568926]
    46,XY,?inv(20).fib ish inv(20)(p12.2p13)(D20S181 sp con JAG1 sp, 6b6+, D20S181 sp con JAG1 sp).
    The patient was 4 years old. It appears that disruption of JAG1, loss of function mutations or deletion resulting in haploinsufficiency, causes the expression of AGS.
    Aberration: Inversion paracentric
    MIM#: 118450
    Index Terms: JAG1,Alagille syndrome
