Bir keçide hermafroditizm olgusu: Klinik ve genetik yaklaşım

Year 2014, Volume: 30 Issue: 4, 227 - 231, 01.12.2014

Abstract

Bu vaka takdiminde, 2010 yılında Selçuk Üniversitesi, Veteriner
Fakültesi, Doğum ve Jinekoloji Kliniğine getirilen ve hermafroditizm
olgusu saptanan Maltız melezi bir keçinin klinik
muayenesi ile sitogenetik ve moleküler genetik analizleri ger-
çekleştirildi. Anamnezde keçinin tek olarak doğduğu, klinik
muayenede boynuzsuz, klitorisin 1.9x0.9 cm büyüklüğünde,
vajinanın normalden daha kısa olduğu gözlendi. Palpasyon
ve ultrasonografik muayenede inguinal bölgede, deri altında
sağ (4.88 cm) ve sol (2.87 cm) testis tespit edildi. Meme ve
meme başları normal konumunda ve büyüklükte belirlendi.
Deri altı rüdimenter penis varlığı tespit edildi, ancak scrotum
ve açık prepisyum gözlenmedi. Karyotip analizi için periferik
kandan hazırlanan kromozom preparatları GTG bantlama
tekniği ile boyanmış ve image analyzer programı ile uygun
metafazlar belirlenerek analiz edildi. Kan örneğinden DNA
izolasyonu geçekleştirildi, sex-determining region Y (SRY) ve
amelogenin gen bölgeleri pozitif ve negatif kontroller kullanılarak
polimeraz zincir reaksiyonu (PZR) ile yükseltgendi.
Karyotip analizinde metafaz plağı 60,XY olarak tespit edildi.
PZR analizlerinde SRY lokusu negatif, amelogenin lokusunda
ise yalnızca AMX alleli tespit edildi. Keçilerde yaygın olarak
gözlenen hermafroditizm vakalarının şekillenmesinde farklı
mekanizmalar bildirilmektedir. Hermafroditizm vakalarının
karyotip ve moleküler genetik analizler ile detaylı incelenmesi
ve boynuzsuz keçilerin damızlıktan çıkarılması tavsiye
edilmektedir.

A case report of hermaphrodite goat: Clinical and genetic approach

Year 2014, Volume: 30 Issue: 4, 227 - 231, 01.12.2014

Abstract

This case report describes clinical examination and cytogenetic
and molecular genetic analyses of a hermaphrodite
mixed Maltese breed goat that was referred to the Gynecology
Clinic of the Faculty of Veterinary Medicine, Selcuk University
in 2010. In anamnesis, goat was a single kid at the birth
and was polled. Clitoris was 1.9x0.9 cm in size and vagina
was shorter than normal. By palpation and ultrasonographic
examination, it was determined that the right (4.88 cm) and
left (2.87 cm) testicles were located under skin in the inguinal
region. Breast and nipples were in normal size. There
was a rudimentary penis located under skin but no scrotum
or prepitium was observed. After chromosome preparation
using peripheral blood samples and GTG staining, appropriate
metaphases were analyzed using an image analyzer program.
Genomic DNA was isolated from the blood sample. Sexdetermining
region Y (SRY) and amelogenin gene regions
were amplified using polymerase chain reaction (PCR) including
positive and negative controls. In karyotype analysis,
metaphase plaque was observed as 60,XY. In PCR analysis, no
SRY amplification was determined and only AMX allele was
observed for amelogenin locus. Hermaphroditism is widely
observed in goats and a number different mechanisms were
reported. It is suggested that polled rams should be culled
and karyotype and molecular genetics analyses should be
performed to evaluate hermaphrodite cases in detail.
