We report here a Down syndrome with karyotype, 46,XX,-14,-22,+der t dic(14p;22p)pat, +21. Proband's father, two sisters, and a brother are phenotypically normal, heterozygous carriers for dicentric t(14;22). This is the only case of a translocation t(14;22) with regular trisomy 21 in our series of 600 Down syndrome cases investigated.

Karyotype of human with Trisomy 21 (Down Syndrome) Trisomy 21, also known as Down Syndrome, is a genetic disorder that occurs when a person has 47 chromosomes instead of the 46 normal chromosomes. In a normal human cell there are 23 pairs of chromosomes that contain genetic information.

Trisomy 21 due to translocation: de novo or transmitted from a parental translocation (being a balanced translocation in the parent); genetic coonseling is especially needed in the latter case. karyotype with 46 chromosomes; the extra chromosome 21 is most often translocated with another acrocentric (groupe D: 14, 13 or 15 or groupe G: 21 or 22) chromosome; example: 46, XY, t(14;21). Down syndrome or Down's syndrome, also known as trisomy 21, is a genetic disorder caused by the presence of all or part of a third copy of chromosome 21. It is usually associated with physical growth delays, mild to moderate intellectual disability, and characteristic facial features. Figure ï ò.: Chromosome picture (karyotype) from a female with trisomy 21. In this cell, there are 47 chromosomes including three copies of chromosome 21 instead of the usual two. Some people have Down syndrome as a result of a Robertsonian translocation.

Diagnosis is suggested by physical anomalies and abnormal development and confirmed by cytogenetic analysis. Management depends on specific manifestations and anomalies. 1. Endokrynol Pol. 1980 May-Jun;31(3):279-83.

trisomy 21 mosaicism (mosaic down syndrome) Trisomy 21 (Down Syndrome) is the most common chromosomal abnormality amongst livebirths, with an incidence of 1/800. It is estimated that 80% of all trisomy 21 pregnancies conceived end as spontaneous abortions or as stillbirths; approximately 2% of spontaneous abortions and 1% of stillbirths will have trisomy 21.

An extra chromosome 13 is observed with a pair of autosomal chromosome number 13.
