Abstract. The Fragile X (FRAXA) syndrome is the most common cause of familial (monogenic) mental retardation and is widespread in human populations. This syndrome is characterised by an unusual mode of transmission for an X-linked disease.
There are four levels of ID:mild.moderate.severe.profound.
People with moderate intellectual disability have fair communication skills, but cannot typically communicate on complex levels. They may have difficulty in social situations and problems with social cues and judgment.
The term “mental” is replaced by the term “intellectual” and “retardation” by the phrase “disorder of development.” The new ICD-11 term is similar to “Intellectual Developmental Disorder” (IDD) used by DSM-5....Article Access StatisticsCited by others713 more rows•Nov 20, 2018
Intellectual disability 1 involves problems with general mental abilities that affect functioning in two areas: Intellectual functioning (such as learning, problem solving, judgement). Adaptive functioning (activities of daily life such as communication and independent living).
F70 Mild mental retardation Approximate IQ range of 50 to 69 (in adults, mental age from 9 to under 12 years). Likely to result in some learning difficulties in school.

Fragile X syndrome (FXS), also known as Martin-Bell syndrome, or Escalante's syndrome (more commonly used in South American countries), is a genetic syndrome. Nearly half of all children with fragile X syndrome meet the criteria for a diagnosis of autism. It is an inherited cause of intellectual disability especially among boys. It results in a spectrum of intellectual disabilities ranging from mild to severe as well as physical characteristics such as an elongated face, large or protruding ears, and large testes (macroorchidism), and behavioral characteristics such as stereotypic movements (e.g. hand-flapping), and social anxiety.
Fragile-X Syndrome. In addition to being associated with characteristic physical and behavioural features, Fragile-X syndrome causes intellectual disabilities ranging from mild to severe. It is the most common cause of inherited intellectual disability and is second only to Down's syndrome as the most common genetic cause of intellectual disability.
Females: Approximately 50 percent of women with the full mutation have IQs in the borderline or mild intellectual disability range (Hagerman et al., 1992). Affected females without intellectual disability may have specific deficits in the areas of attention, visuo-spatial skills and executive functions.
FXS is an X-linked semi-dominant condition with reduced penetrance. It is caused by an expansion of an unstable CGG trinucleotide repeat in the fragile X gene (FMR-1). In addition to being associated with characteristic physical and behavioural features, causes intellectual disability ranging from mild to severe. It is the most common cause of inherited intellectual disability and is second only to Down’s syndrome as the most common genetic cause of intellectual disability. There is a wide spectrum of clinical features, but life expectancy is not greatly reduced.
The average IQ in adult men with the completely methylated full mutation is approximately 40 (Merenstein et al., 1996). Specific cognitive profiles show that they have particular difficulties in sequential processing, with short-term memory deficits manifesting as a weakness in arithmetic. In spite of the reported decline in IQ test scores with age, adaptive behaviour improves with appropriate training. Although there is no correlation between the size of the CGG repeat (within the full mutation range) and degree of intellectual impairment in males, lower expression of FMRP is thought to correlate with IQ in mosaic males and males with a partially methylated full mutation.
Of the other nearby fragile sites identified on the X chromosome, namely FRAX-D, FRAX-E and FRAX-F, only the FRAX-E mutation is associated with intellectual disability (Figure 2). Distinguishing these sites from FRAX-A on standard chromosome cultures has become easier with improving techniques, especially fluorescent in situ hybridization (FISH).
FXS is an X-linked, dominantly inherited disorder, with reduced penetrance, but its pattern of inheritance is atypical. Both females and males can be affected, although it is less common and often less severe in females. In addition, both males and females can be unaffected carriers. Four-fifths of males with the full mutation are clinically affected, while only half the females with the full mutation are affected. In females with the premutation, the CGG trinucleotide expansion in the FMR-1 gene is hereditarily unstable. There is, therefore, a high risk of the premutation expanding to a full mutation when it is transmitted from a woman to her children. However, when the premutation is passed through men (also known as carrier males or normal-transmitting males), it does not significantly increase in size. The sons of an unaffected man do not receive the X chromosome and so are neither affected nor carriers. His daughters, on the other hand, receive the premutation and are all unaffected carriers, although their own children are at risk of inheriting the full mutation. Heterozygous females who receive the full mutation from their mothers may have clinical features of FXS. The transmission of the mutation through phenotypically normal daughters to their grandchildren, (the so-called Sherman paradox, or ‘genetic anticipation’) occurs when the disease severity increases through successive generations. About 25% of female carriers have intellectual disability, and they are more likely to have similarly affected offspring than are intellectually normal carrier females.
Intellectual disability (ID), also called intellectual development disorder (IDD) or general learning disability, and formerly known as mental retardation (MR), is a generalized neurodevelopmental disorder characterized by significantly impaired intellectual and adaptive functioning. It is defined by an IQ score below 70 in addition to deficits in two or more adaptive behaviors that affect everyday, general living. Once focused almost entirely on cognition, the definition now includes both a component relating to mental functioning and one relating to individuals' functional skills in their environments. As a result of this focus on the person's abilities in practice, a person with an unusually low IQ may not be considered intellectually disabled. Intellectual disability is subdivided into syndromic intellectual disability, in which intellectual deficits associated with other medical and behavioral signs and symptoms are present, and non-syndromic intellectual disability, in which intellectual deficits appear without other abnormalities. Down syndrome and fragile X syndrome are examples of syndromic intellectual disabilities.
