Congenital Generalized Hypertrichosis Type Ambras

Ambras Syndrome


Presentation

  • This illustrates the need to accurately determine the type of excess hair present on a given patient.[thehealthscience.com]
  • We report a case of transient neonatal cutis laxa and hypertrichosis lanuginosa as an initial presentation in Sotos syndrome. Little is known about skin involvement in Sotos syndrome.[pubfacts.com]
  • The congenital form of the disease is extreme rare and is always present at birth. Acquired Ambras syndrome develops after birth and is often associated with medication side effects, eating disorders and cancer.[babymed.com]
  • Facial and dental abnormalities may also be present. Ambras syndrome has been mapped to the short (q) arm of chromosome 8. It appears to follow an autosomal dominantpattern of inheritance.[checkorphan.org]
Microdontia
  • […] bilateral enlargement of the palatal mucosa may meet in the midline. [8] A variety of dental findings have been described in relation to congenital hypertrichosis lanuginose, including delayed eruption of permanent teeth, hypodontia, neonatal teeth, microdontia[jisppd.com]
Hirsutism
  • More common causes of hirsutism include polycystic ovary syndrome (PCOS), idiopathic hirsutism, hyperprolactinemia, hyperthecosis, and medications (eg, danazol, androgenic oral contraceptives).[thehealthscience.com]
  • Hypertrichosis differs from Hirsutism in that, it is not androgen related and does not follow the male pattern of Hair distribution, while Hirsutism commonly occurs in women and presents as androgen-induced male pattern hair growth.[impocity.blogspot.com]
  • Affiliated tissues include skin and eye , and related phenotypes are congenital, generalized hypertrichosis and hirsutism OMIM : 57 Hypertrichosis is defined as hair growth that is excessive for a particular site of the body or age of the patient and[malacards.org]
  • Hirsutism is quantified by the Ferriman–Gallwey scale, with scores of 6–8 considered mildly hirsute, 8–15 serious, and 15 overt hirsutism. Other signs of hyperandrogenism are acne, oligo- or amenorrhea, and androgenetic alopecia.[en.tzermias.gr]
  • Hirsutism Hypertrichosis is often mistakenly classified as hirsutism. [ 1 ] Hirsutism is a type of hypertrichosis exclusive to women and children, resulting from an excess of androgen sensitive hair growth. [ 16 ] Patients with hirsutism exhibit patterns[thefullwiki.org]
Cutis Laxa
  • Our observation highlights that Sotos syndrome is a rare cause of cutis laxa and suggests that it is a useful neonatal skin clue to the diagnosis of overgrowth syndromes.[pubfacts.com]
Thin Lips
  • The features include distinctive faces, secondary to a low hairline, penciled but not bushy eyebrows, long eyelashes and thin lips. They also have relatively constant abnormalities like mental and growth retardation.[hypertrichosis.com]
Prominent Nasal Root
  • He also had dysmorphic facial features like triangular facies and coarse features, hypertelorism, a wide and prominent nasal root, a large interalar distance, round nasal tip and anteverted nostrils. [Figure 1] and [Figure 2] depict these features.[mjdrdypu.org]

Workup

  • Down regulation of TRPS1 expression is the probable cause of hypertrichosis in Ambras syndrome. [6] The diagnosis is based on clinical and histologic findings, and no laboratory workup or imaging studies is necessary, except to exclude other causes of[mjdrdypu.org]

Etiology

  • ., who described the etiology as specific genetic alteration, that is, pericentric inversion (8) (p11.2; q22,) and can also be due to fetal alcohol syndrome and fetal hydentoin syndrome. [3], [4] AS is characterized by increase in vellous type of hair[jisppd.com]
  • A genetic etiology is proposed for Ambras syndrome. It is associated with alterations in chromosome 8 as analyzed in 2 out of 10 cases so far.[mjdrdypu.org]
