What is Trisomy 18?
Ata: What is Trisomy 18?

O le Trisomy 18 ose faʻamaʻi lea e iai le kopi lona tolu a le tagata mai le chromosome 18, ae leʻo le kopi masani e 2. Tele o mataupu e le tuʻufaʻatasia e aiga. Ae ui i lea, o faʻafitauli e mafua ai lenei tulaga e tupu i le sperm poʻo le fuamoa e fausia ai le pepe.

Trisomy 18 tupu i le 1 i le 6000 ola fananau mai. E 3 taimi sili atu taatele i teine ​​nai lo tama.

E tupu le faʻamaʻi pe a iai ni faʻaopoopoga mea mai le chromosome 18. O mea faʻaopopo e afaina ai le atinaʻe masani.

  • Trisomy 18: o le i ai o se faʻaopopo (tolu) chromosome 18 i sela uma.
  • Mosaic trisomy 18: o le i ai o le sili atu chromosome 18 i nisi o sela.
  • Partial trisomy 18: o le i ai o se vaega o le faʻaopoopo chromosome 18 i sela.

Ole tele o mataupu ole Trisomy 18 e le pasia e aiga (tofi). Nai lo lena, o mea na tutupu e taitai atu ai i le trisomy 18 tupu i le sperm po o le fuamoa e fausia ai le fetus.

Faʻailoga e ono aofia ai:

  • Lima uumau
  • Koluse vae
  • O vae ma le lapotopoto o lalo (rocker-lalo vae)
  • Paʻu maualalo ole mamafa
  • Taliga maualalo
  • Faatuai o le mafaufau
  • Le lelei atigilima atigilima
  • Uliʻi ulu (microcephaly)
  • Auvae laiti (micrognathia)
  • Tusitusiga faʻatauvaʻa
  • Le fatafata foliga foliga (pectus carinatum)

O se suʻega i le taimi o le maitaga atonu e faʻaalia ai le tele tele o le toʻa ma faʻaopopo vai suamalie. Atonu e iai se laʻititi laiti pe a fanau le pepe. O se suʻega faʻapitoa o le pepe e ono faʻaalia foliga le masani ai ma foliga o tamailima. X-ave e ono faʻaalia ai se ponaivi o le ponaivi.


O suʻesuʻega a le Chromosome o le a faʻaalia ai le trisomy 18. O le chromosome abnormal e ono iai i sela uma pe o loʻo iai i le na o se pasene o sela (e taʻua o le mosaicism). E mafai foʻi ona faʻaalia i suʻesuʻega se vaega o le chromosome i nisi sela. E seasea lava, o se vaega o le chromosome 18 e faʻapipiʻi i se isi chromosome. E taʻu lea ole translocation.

Isi faʻailoga aofia ai:

  • Faʻavae, vaelua, pe vaeluaina i le iris o le mata (coloboma)
  • Vavaeʻese i le va o le agavale ma le itu taumatau o le manava maso (diastasis recti)
  • Hnia faʻafilemu poʻo inguinal hernia

E masani ona iai faʻailoga ole maʻi fatu ole fanau mai, e pei ole:

  • Atrial septal faaletonu (ASD)
  • Patent ductus arteriosus (PDA)
  • Faʻaletonu septric Ventricular (VSD)

O suʻega e ono faʻaalia ai foʻi faʻafitauli tau fatugaʻo, e aofia ai:

  • Horseshoe fatugaʻo
  • Hydronephrosis
  • Fatugaʻo Polycystic

E leai ni faʻapitoa togafitiga mo trisomy 18. O fea togafitiga e faʻaogaina faʻamoemoeina i le tagata lava ia tulaga.


Vaega lagolago aofia ai:

  • Lagolago Faʻalapotopotoga mo Trisomy 18, 13 ma Fesoʻotaʻiga Fesoasoani (SOFT): trisomy.org
  • Trisomy 18 Foundation: www.trisomy18.org
  • Faamoemoe mo Trisomy 13 ma 18: www.hopefortrisomy13and18.org

Tasi le afa o pepe ma lenei tulaga e le mafai ona ola i tala atu o le muamua vaiaso o le olaga. E toaiva mai le toasefulu tamaiti o le a maliliu i le 1 tausaga le matutua. O nisi tamaiti na sao mai tausaga talavou, ae o loʻo iai faʻafitauli faigata ile soifua maloloina ma le atinaʻe.

Faʻalavelave faʻalagolago i luga o le faʻapitoa vaivaiga ma auga.

Faʻafitauli e ono aofia ai:

  • Manava manava pe leai se manava (apnea)
  • Tutuli
  • Fafagaina faʻafitauli
  • Le lava le fatu
  • Faoa faamalosi
  • Faʻafitauli vaʻai

O fesoasoani faʻavae e mafai ona fesoasoani i aiga ia malamalama i le tulaga, mea lamatia o le mautofi ai, ma pe faʻafefea ona tausi le tagata.

E mafai ona faia faʻataʻitaʻiga i taimi o maʻito e iloa ai pe ua maua le tamaititi i lenei faʻamaʻi.

Ole fautuaga faʻapitoa e fautuaina mo matua o loʻo iai se tamaititi e maua ile faʻamaʻi lenei ma e manaʻo foʻi ia maua nisi fanau.
