An inherited condition with a strange-sounding name, the Nail-Patella Syndrome is more commonly referred to by its acronym, NPS. This ailment affects not just the knees and elbows but also the pelvis as well as a variety of other body locations, including the elbows and knees.
As we are going to discover, some conditions can also have an effect on one’s sight, as can be shown in this particular example. Because it can be passed on from one generation to the next, it frequently shows up in children, although it does not always do so in the same way. The condition can present itself in a wide variety of ways. It frequently goes misdiagnosed for a considerable amount of time. In some cases, this can go on for decades.

Nail patella syndrome: what is it?
There are several other names for what is medically known as “nail-patella syndrome,” but they all pertain to the same illness.
Hereditary onychoosteodysplasia (HOOD) is a condition that has several names in the medical community. Let’s get to the bottom of what’s causing this sickness and what it means.
When does NPS onset?
The nail-patella syndrome is an autosomal dominant genetic disease. This means that the presence of a single gene (as opposed to the usual requirement of two) is sufficient to cause the disease in the progeny.
According to this reasoning, if one parent has the disease, the offspring have a 50% probability of also getting it. Nearly 88% of the sick people would have inherited the disease from an affected parent, and the remaining 2% would have acquired it through genetic mutation, according to some studies.
There is no known vector for this illness. Although research is ongoing, LMX1B has so far been identified as the only gene associated with this disorder. This gene acts as a watchdog for the protein that guides the embryo’s developing limbs.
The painful signs of nail-patella syndrome
Patients can display a wide variety of symptoms from this condition. Here are a few examples:
Disorders of the nails
This is the one symptom of NPS that will always be present. This genetic disorder almost always affects fingernails, particularly the thumbs, although it only occasionally manifests itself in the toenails. As the affected individual gets older, the symptoms spread from the thumb to the fingernails.
The nails will have pitting and ridging if dysplasia is present. Dysplasia is another name for underdevelopment. They frequently vanish completely or can only be seen as a thin, distinct line near the cuticle.
They’ve also lost their color and cracked. Patients who have this condition generally have nail lunula that have the shape of a triangle, as opposed to the more typical crescent shape.
Defects in the skeletal system
The patellae (kneecaps) are the second most common target of the NPS, behind the nails themselves. Some patients also experience patella displacement in addition to weak, uneven, or nonexistent kneecaps (a condition known as hypoplasia).
However, cubitus valgus, or a protruding elbow, may be present. Patients in this category frequently have abnormal hand postures, such as palms-up hand gestures. This occurs when the radia are abnormally produced, and it is accompanied by a webbed area of skin at the elbow joint.
It is possible to discern hornlike protrusion from the iliac bones in the pelvic region. Underdeveloped shoulder blades and a bent spine (scoliosis) are two potential consequences of nail-patella syndrome.
Eye conditions
Some glaucoma patients also have cataracts. This occurs because the outward flow of the fluid (also called the aqueous humor) from the front chamber of the eye is obstructed, leading to a rise in the pressure behind the eye.
Without treatment, blindness is a possible outcome. Nail-patella condition is also linked to Lester’s Sign, a form of eye problems. The iris darkens in general and develops a cloverleaf-shaped area as a symptom of this illness. Fortunately, this does not cause any visual impairment.
Renal issues
The kidneys are essential for purifying the body’s blood, and between 30 and 50 percent of individuals with patella syndrome also report kidney difficulties. These can be caused by the wasting away of renal tubules or by the swelling and eventual degeneration of the capillaries.
Blood in the urine, skin edema, and elevated blood pressure are the most obvious outward manifestations of NPS. Surprisingly, the patient may be the last person to notice anything is wrong.
Early childhood diagnosis is possible, as is late-life diagnosis. The patient’s body and family history, in addition to laboratory tests and clinical observations, are used to arrive at a diagnosis.
The nail-patella syndrome calls for a team effort from medical professionals, with each expert tending to a different portion of the body. Surgery has the potential to correct the problem in some people. However, a timely diagnosis is always preferable for the sake of the patient.
