XX male syndrome

Index XX male syndrome

XX male syndrome is a rare congenital condition where an individual with a female genotype has phenotypically male characteristics that can vary between cases. [1]

Androgen insensitivity syndrome

Androgen insensitivity syndrome (AIS) is an intersex condition in which there is a partial or complete inability of many cells in the affected genetic male to respond to androgenic hormones.

Autosome

An autosome is a chromosome that is not an allosome (a sex chromosome).

Chromosomal crossover

Chromosomal crossover (or crossing over) is the exchange of genetic material between homologous chromosomes that results in recombinant chromosomes during sexual reproduction.

Chromosomal translocation

In genetics, a chromosome translocation is a chromosome abnormality caused by rearrangement of parts between nonhomologous chromosomes.

Clitoromegaly

Clitoromegaly (or macroclitoris) is an abnormal enlargement of the clitoris that is mostly congenital or acquired, though deliberately induced clitoris enlargement as a form of female genital body modification is achieved through various uses of anabolic steroids, including testosterone, and may also be referred to as clitoromegaly. Clitoromegaly is not the same as normal enlargement of the clitoris seen during sexual arousal.

Cytogenetics

Cytogenetics is a branch of genetics that is concerned with how the chromosomes relate to cell behaviour, particularly to their behaviour during mitosis and meiosis.

DAX1

DAX1 (dosage-sensitive sex reversal, adrenal hypoplasia critical region, on chromosome X, gene 1) is a nuclear receptor protein that in humans is encoded by the NR0B1 gene (nuclear receptor subfamily 0, group B, member 1).

Fluorescence in situ hybridization

Fluorescent in situ hybridization (FISH) is a molecular cytogenetic technique that uses fluorescent probes that bind to only those parts of the chromosome with a high degree of sequence complementarity.

Genotype

The genotype is the part of the genetic makeup of a cell, and therefore of an organism or individual, which determines one of its characteristics (phenotype).

Gynecomastia

Gynecomastia is an endocrine system disorder in which a noncancerous increase in the size of male breast tissue occurs.

Hermaphrodite

In biology, a hermaphrodite is an organism that has complete or partial reproductive organs and produces gametes normally associated with both male and female sexes.

Homologous recombination

Homologous recombination is a type of genetic recombination in which nucleotide sequences are exchanged between two similar or identical molecules of DNA.

Hypospadias

Hypospadias is a congenital disorder of the urethra where the urinary opening is not at the usual location on the head of the penis.

Infertility

Infertility is the inability of a person, animal or plant to reproduce by natural means.

Inguinal canal

The inguinal canals are the two passages in the anterior abdominal wall which in males convey the spermatic cords and in females the round ligament of uterus.

Karyotype

A karyotype is the number and appearance of chromosomes in the nucleus of a eukaryotic cell.

Klinefelter syndrome

Klinefelter syndrome (KS) also known as 47,XXY or XXY, is the set of symptoms that result from two or more X chromosomes in males.

Meiosis

Meiosis (from Greek μείωσις, meiosis, which means lessening) is a specialized type of cell division that reduces the chromosome number by half, creating four haploid cells, each genetically distinct from the parent cell that gave rise to them.

Micropenis

Micropenis is an unusually small penis.

Null allele

A null allele is a nonfunctional copy of a gene caused by a genetic mutation.

Paramesonephric duct

Paramesonephric ducts (or Müllerian ducts) are paired ducts of the embryo that run down the lateral sides of the urogenital ridge and terminate at the sinus tubercle in the primitive urogenital sinus.

Phenotype

A phenotype is the composite of an organism's observable characteristics or traits, such as its morphology, development, biochemical or physiological properties, behavior, and products of behavior (such as a bird's nest).

Ploidy

Ploidy is the number of complete sets of chromosomes in a cell, and hence the number of possible alleles for autosomal and pseudoautosomal genes.

SF1 (gene)

Splicing factor 1 also known as zinc finger protein 162 (ZFM162) is a protein that in humans is encoded by the SF1 gene.

Testis-determining factor

Testis-determining factor (TDF), also known as sex-determining region Y (SRY) protein, is a DNA-binding protein (also known as gene-regulatory protein/transcription factor) encoded by the SRY gene that is responsible for the initiation of male sex determination in humans.
