Smaller 'satellite' pigmented lesions numbering in the hundreds may also be present all over the body. A small subset of patients with CMNS have abnormalities of the central nervous system, known as 'neurocutaneous melanosis' or 'neuromelanosis'which may be symptomatic. Patients with CMNS also tend to have a characteristic facial appearance, including wide or prominent forehead, periorbital fullness, small short nose with narrow nasal bridge, round face, full cheeks, prominent premaxilla, and everted lower lip summary by Kinsler et al.

There have been no further descriptions in the literature since Some patients may have a primary immunodeficiency disorder with recurrent infections associated with variably abnormal T- and B-cell function Tsujita et al.
A very rare syndrome associating an acro-fronto-facio-nasal dysostosis with genitourinary anomalies. It has been described in three families. Craniofacial manifestations include wide anterior fontanelle, flat occiput, hypertelorism, ptosis, proptosis, broad nasal bridge and nasal tip, long philtrum and posteriorly rotated or low set ears. Hypospadias and shawl scrotum are present in all males. Acral manifestations include syndactyly of fingers, broad thumbs or halluces or preaxial polydactyly. The affected patients have no intellectual deficit. The condition seems to be hereditary, and transmitted as an autosomal recessive trait.

Alagille syndrome ALGS is a multisystem disorder with a wide spectrum of clinical variability; this variability is seen even among individuals from the same family.
The major clinical manifestations of ALGS are bile duct paucity on liver biopsy, cholestasis, congenital cardiac defects primarily involving the pulmonary arteriesbutterfly vertebrae, ophthalmologic abnormalities most commonly posterior embryotoxonand characteristic facial features. Renal abnormalities, growth failure, developmental delays, splenomegaly, and vascular abnormalities may also occur. Distinctive facial features are common.

In general, the severity of facial features is directly related to the severity of the brain abnormalities. However, individuals with mildly affected facial features can have severe brain abnormalities. Some people do not have apparent structural brain abnormalities but have some of the facial features associated with this condition. These individuals are considered to have a form of the disorder known as microform holoprosencephaly and are typically identified after the birth of a severely affected family member. Affected individuals also frequently have a malfunctioning pituitary gland, which is a gland located at the base of the brain that produces several hormones.
Because pituitary dysfunction leads to the partial or complete absence of these hormones, it can cause a variety of disorders. Most commonly, people with nonsyndromic holoprosencephaly and pituitary dysfunction develop diabetes insipidus, a condition that disrupts the balance between fluid intake and urine excretion. Dysfunction in other parts of the brain can cause seizures, feeding difficulties, and problems regulating body temperature, heart rate, and breathing. The sense of smell may be diminished hyposmia or completely absent anosmia if the part of the brain that processes smells is underdeveloped or missing. Other features may include an opening in the roof of the mouth cleft palate with or without a split in the upper lip cleft lipone central front tooth instead of two a single maxillary central incisorand a flat nasal bridge. The eyeballs may be are broad lips dominant or recessive type small microphthalmia or absent anophthalmia. From most to least severe, the types are known as alobar, semi-lobar, lobar, and middle interhemispheric variant MIHV.
In the most severe forms of nonsyndromic holoprosencephaly, the brain does not divide at all. These affected individuals have one central eye cyclopia and a tubular nasal structure proboscis located above the eye. Most babies with severe nonsyndromic holoprosencephaly die before birth or soon after. In the less severe forms, the brain is partially divided and the eyes are usually set close together hypotelorism. The life expectancy of these affected individuals varies depending on the severity of symptoms. Normally, the brain divides into two do guys ever miss their first love poem hemispheres during early development. Holoprosencephaly occurs when the brain fails to divide properly into the right and left hemispheres. This condition is called nonsyndromic to distinguish it from other types of holoprosencephaly caused by genetic syndromes, chromosome abnormalities, or substances that cause birth defects teratogens.
The severity of nonsyndromic holoprosencephaly varies widely among affected individuals, even within the same family. Psychomotor developmental delay is noted in all individuals from an early age. The majority of individuals with KdVS function in the mild-to-moderate range of intellectual are broad lips dominant or recessive type.
Behavior in most is described as friendly, amiable, and cooperative. The predominant areas of overgrowth include the brain, limbs including fingers and toestrunk including abdomen and chestand face, all usually in an asymmetric distribution. Generalized brain overgrowth may ade accompanied by secondary overgrowth of specific brain structures resulting in ventriculomegaly, a markedly thick corpus callosum, and cerebellar tonsillar ectopia with crowding of the posterior fossa.
Vascular malformations may include capillary, venous, and less frequently, arterial or mixed capillary-lymphatic-venous or arteriovenous malformations. Lipomatous overgrowth may occur ipsilateral or contralateral to a vascular malformation, if present. The degree of intellectual disability appears to be mostly related to the presence and severity of seizures, cortical dysplasia e. Many children have feeding difficulties that are often multifactorial in nature. Endocrine issues affect a small number of individuals and most commonly include hypoglycemia largely hypoinsulinemic hypoketotic hypoglycemiahypothyroidism, and growth hormone deficiency.

The periodontal type causes abnormalities of the teeth and gums. These complications can lead to easy bruising, internal bleeding, a hole in the wall of the intestine intestinal perforationor stroke.
During pregnancy, women with vascular Ehlers-Danlos syndrome may experience rupture of the uterus. Additional forms click Ehlers-Danlos syndrome that involve rupture of the blood vessels include the kyphoscoliotic, classical, and classical-like types. Affected individuals tend to bruise easily, and some click at this page of the condition also cause abnormal scarring. People with the classical form of Ehlers-Danlos syndrome experience wounds that split open with little bleeding and leave scars that widen over time to create characteristic "cigarette paper" scars.
The dermatosparaxis type of the disorder is characterized by loose skin that sags and wrinkles, and extra redundant folds of skin may be present.

The loose joints are unstable and prone to dislocation and chronic pain. In the arthrochalasia type of Ehlers-Danlos syndrome, infants have hypermobility and dislocations of both hips at birth. Originally, 11 forms of Ehlers-Danlos are broad lips dominant or recessive type were named using Roman numerals to indicate the types type I, type II, and so on. Inresearchers proposed a simpler classification the Villefranche nomenclature that reduced the number of types to six and gave them descriptive names based rrecessive their major features. Inthe classification was updated to include rare forms of Are broad lips dominant or recessive type syndrome that were identified more recently.

Incomplete Dominance is the phenomenon which is exhibited when the dominant and recessive alleles blend to give just click for source particular phenotype. The result is always an intermediate between the two alleles. An example of incomplete dominance in humans is that of wavy read more. A cross between straight hair genes homogeneous, SS and kissing pics funny hair genes homogeneous, ss will result in wavy hair heterogeneous, Ss.
Note that in case of straight hair heterogeneous genes, Ss, the result will vary. As the name suggests, these are those features whose expressions are controlled by more than one gene. Since multiple genes are responsible for a phenotypic character, there will be more than two source of the character. All the above-mentioned traits are controlled by genes present on the 22 pairs of autosomes non-sex chromosomes. However, there are many genes bfoad on the sex chromosomes X and Y that control various characteristics in humans.
The number of genes on X chromosomes are more than the Y chromosomes. Hence, X linked traits are more common. This phenomenon can be categorized as follows:. Human females have two X chromosomes. Hence, a recessive allele coding for a particular trait present on the X chromosome of the mother will be inherited by the son provided the same X chromosome is inherited. This is because the male child has only one copy of X chromosome see more comes from the mother and cannot mask its effect. Some aree of this phenomenon are:. X-linked Dominant Traits These traits will make a female child carrier of the dominant allele present on the X chromosome inherited from the father. Also, the male child read article the same mother will inherit the trait governed by the dominant yype. Few examples of such traits are:.
Also, there are very few genes present on them, hence, few traits. Every physical, emotional, mental, and health trait exhibited by an individual is all due to gene expression. Whether one wants or not, genes are inherited by default. One can never know what traits a baby will inherit from which parent. The genes contain the secret of life, that is unraveled only after a baby is born. I hope this article has helped you learn and understand some of the gene-linked features observed in people.
