A

due to a defect in the co-migration of GnRH releasing neurons and olfactory neurons that occurs during early foetal development

172
Q

ANDROGEN INSENSITIVITY SYNDROME
what is it?

A

a genetic condition in which there are defects in the androgen receptor
- is x-linked recessive
- patients are genetically male (46XY)but develop female phenotype

173
Q

ANDROGEN INSENSITIVITY SYNDROME
what is complete AIS?

A
  • karyotype = 46XY
  • results in a completely female phenotype
  • external genitalia are female (clitoris, hypoplastic labia majora + blind-ending vagina)
  • testes may be present in abdomen
  • absence of pubic + axillary hair
  • normal breast development
174
Q

ANDROGEN INSENSITIVITY SYNDROME
what is partial AIS?

A
  • presents with a wide range of phenotypes
  • can present as normal male with fertility issues
  • sex assignment depends on the degree of genital ambiguity
175
Q

ANDROGEN INSENSITIVITY SYNDROME
what is true hermaphroditism?

A
  • have both ovarian tissue with follicles and testicular tissue with seminiferous tubules, either in the same organ or one on either side
  • external genitalia are often ambiguous
176
Q

ANDROGEN INSENSITIVITY SYNDROME
what is the inheritance pattern?

A

x-linked recessive

177
Q

ANDROGEN INSENSITIVITY SYNDROME
what are the results of hormone tests?

A
  • raised LH
  • normal/raised FSH
  • normal/raised testosterone
  • raised oestrogen
178
Q

FRAGILE X SYNDROME
What causes it?

A

Trinucleotide expansion repeat of CGG caused by slipped mispairing = ≤44 normal, 60–200 = premutation carriers, >200 = fragile X

179
Q

PRECOCIOUS PUBERTY
What are the causes in females?

A

More common in girls, usually idiopathic or familial, occasionally late presenting CAH

180
Q

PRECOCIOUS PUBERTY
What are the causes in males?

A

Less common, more worrying
– Pituitary adenoma (bilateral testicular enlargement suggests gonadotropin release)
– CAH or adrenal tumour (small testes)
– Gonadal tumour (unilateral testicular enlargement)

181
Q

PRECOCIOUS PUBERTY
What is a genetic cause of precocious puberty?

A

McCune Albright syndrome (café-au-lait, short stature)

182
Q

HYPOGONADISM
Name the 3 types of hypogonadism?

A

Primary = hypergonadotropic hypogonadism
Secondary = hypogonadotropic hypogonadism
Tertiary = hypogonadotropic hypogonadism

183
Q

GONADOTROPIN DEFICIENCY
What is Hypergonadotropic hypogonadism?

A

Primary gonadal failure - Testes or ovarian failure

184
Q

GONADOTROPIN DEFICIENCY
Give 2 causes of primary hypogonadism

A

Hypergonadotropic hypogonadism

Klinefelter’s Syndrome (47XXY)
Tuner’s Syndrome (45X)

185
Q

GONADOTROPIN DEFICIENCY
What is the effect of Hypergonadotropic hypogonadism on FSH/LH and oestrogen/testosterone levels?

A

FSH/LH = high
Oestrogen/testosterone = low

186
Q

GONADOTROPIN DEFICIENCY
What is Hypogonadotropic hypogonadism?

A

Secondary gonadal failure = problem with pituitary
OR
Tertiary gonadal failure = Problem with hypothalamus

187
Q

GONADOTROPIN DEFICIENCY
Briefly describe the mechanism of secondary hypogonadism

A

Less FSH and LH
So less activation at gonads
Girls = no response to feedback so oestrogen decreases
Boys = no response to feedback so testosterone decreases

188
Q

GONADOTROPIN DEFICIENCY
Briefly describe the mechanism of tertiary hypogonadism

A

Less GnRH produced
So less FSH and LH
So less activation at gonads
Girls = no response to feedback so oestrogen decreases
Boys = no response to feedback so testosterone decreases

189
Q

GONADOTROPIN DEFICIENCY
Give 2 causes of Hypogonadotropic hypogonadism

A
  1. Kallmann’s Syndrome
  2. Tumours - craniopharyngiomas, germinomas
190
Q

GONADOTROPIN DEFICIENCY
What is the effect of hypogonadotropic hypogonadism on FSH/LH and oestrogen/testosterone levels?

A

FSH/LH = low
Oestrogen/testosterone = low

191
Q
