Inherited ichthyosis: Non-syndromic forms

Syndromic and non-syndromic forms of XLMR

| Genetic factors have an important role in the aetiology of mental retardation. However, their contribution is often underestimated because in developed countries, severely affected patients are mainly sporadic cases and familial cases are rare. X-chromosomal mental retardation is the exception to this rule, and this is one of the reasons why research into the genetic and molecular causes of m...

Molecular genetics of syndromic and non‐syndromic forms of parathyroid carcinoma

Parathyroid carcinoma (PC) may occur as part of a complex hereditary syndrome or an isolated (i.e., non-syndromic) non-hereditary (i.e., sporadic) endocrinopathy. Studies of hereditary and syndromic forms of PC, which include the hyperparathyroidism-jaw tumor syndrome (HPT-JT), multiple endocrine neoplasia types 1 and 2 (MEN1 and MEN2), and familial isolated primary hyperparathyroidism (FIHP), ...

Genetic Study of Syndromic Inherited Deafness

The study comprised 25 patients with Syndromic genetic hearing loss. They were selected from the Audiology Unit, Faculty of Medicine, and the Human Genetics clinic, Medical Research Institute, , Alexandria University. Their ages ranged from 2.5 to 19 years. Males were more affected than females (M/F ratio = 2:1). T he high parental consanguinity (63.2 %) emphasizes the contribution of autosomal...

Case Report: Whole exome sequencing helps in accurate molecular diagnosis in siblings with a rare co-occurrence of paternally inherited 22q12 duplication and autosomal recessive non-syndromic ichthyosis.

Lamellar ichthyosis (LI), considered an autosomal recessive monogenic genodermatosis, has an incidence of approximately 1 in 250,000. Usually associated with mutations in the transglutaminase gene ( TGM1), mutations in six other genes have, less frequently, been shown to be causative. Two siblings, born in a collodion membrane, presented with fish like scales all over the body. Karyotyping reve...
