Can Dwarfs Have Children
If a man with achondroplasia and a normal woman children, what is the likelihood of having dwarfs?
50%: If one parent has achondroplasia, a child has a 50 percent chance of inheriting the fgfr3 gene and subsequently developing achondroplasia. If both parents have the disorder, the child has a three in four (75 percent) chance of developing achondroplasia. Also, in these cases, the child has a one in four chance of inheriting the gene from both parents. Newborns who inherit both genes are considered. ...Read more
If a 2 short ppl marry, a female (156cm), and guy (164cm).Will they face the risk of getting children shorter than them or even dwarfs cz they are short?
No: Your children are likely to be shorter than average but taller than you - there is a tendency to move towards the average over generations. This is called "regression to the mean". (no guarantees though!) be sure your baby has good nutrition! the best way is for you to have good nutrition and breast feed. ...Read more
Yes: Dwarf is a term we do not use in medicine anymore because of its despective use outside of medicine, but it was used to describe proportionate short people (mainly pepople with growth hormone deficiency). Growth hormone deficiency can be hereditary bu it can also happen in a spontaneous mutation (no parent or family history). ...Read more
See below: Dwarf is a general term of short stature below 4 1/2 ft (135 cm). Those who have normal body proportions are often called midgets. ...Read more
An adult height: Of less than 4 feet 10 inches maximum is one of the criteria to diagnose dwarfism. ...Read more
If I am normal sized, and have a child with a dwarf, what are the chances our child will be a dwarf?
Several short types: The commonly seen form of achondroplasia is an autosomal dominant form of short limb dwarfism. 80% are new mutations but it can be passed parent to child at a 50%/pregnancy rate. A fetus with a pair of achondroplasia genes has a severe condition & is unlikely to survive infancy. Their are a number of conditions that produce "little people" & you may be thinking of another condition. ...Read more
Little people have: Short stature, usually < 58 " as adults. A variety of genetic conditions cause dwarfism, characterterized by disproportionate body proportions, skeletal anomalies & other medical conditions. "Midget" is a pejorative term for people with proportionate short stature from a variety of genetic, nutritional, & other medical causes. Use " little person" or " a person with. ...", a specific diagnosis. ...Read more
Yes: Internal organs are proportionately in same relative position as normal sized patients. ...Read more
Is it possible for a baby to be born a dwarf and also have down syndrome? How rare is a down dwarf?
Excedingly rare: I had occasion many years ago to investigate such a situation & needed to find answers for why some kids with ds chromosomes (t21) had totally different physical features. Run the numbers: achondroplasia (common new mutation dwarf) @ 1/15, 000 x 1/1700 (risk of ds @ 21)=1/25, 000, 000. ...Read more
Can you tell me if the reproductive system of a dwarf is the same length and size of a average sized female?
Achondroplasia is: The most common form of dwarfism, but there are over 200 types, so you need to specify which type. For A.D., the uterus can be normal size but its placement is abdominal, not pelvic. Penile & testicular size in males with AD can be within normal limits. The lungs can be compromised by malformations of the spine & rib cage, requiring expert care for labor & delivery of a little person female. ...Read more
What to do if I am 5'1 (40+ years old) and I am short. What is the maximum height for someone who is considered a dwarf/little person?
Under 4'10": A dwarf is defined as an adult under 4'10". You are short, but not a dwarf. ...Read more
Possibly: Some types of dwarfism are genetic and range from a dominant trait to a random one. The odds depend on the type of dwarfism. Consult with a specialist in genetics to derive a detailed answer specific to your situation. ...Read more
I am 22nd week pregnant. But the growth of my baby is showing 3 weeks shorter. Is this a case of dwarf.
Possibly: The typical margin of error of u/s at 22 weeks is ten days. If a baby measures outside that margin, and your dates are correct, then conditions that would cause a significantly smaller baby must be considered. The conditions range from chromosome abnormalities to dwarfism to other less serious conditions. This is something to discuss with your OB doctor and/or maternal fetal medicine. ...Read more
I am a 21 year old female. I am only 4'8. Both my mom and grandma are short. My mom being my size and my grandma 4'10. Are we actual dwarfs?
Depends: If you look at one definition, this term is reserved for those whose short stature is due to an unusual condition. This could be lack of growth hormone, a genetic syndrome, the result of chronic kidney disease, etc. If so you are just short. Some use the term quite loosely to describe those at the short end of the normal population. I consider you just short. ...Read more
Yes: It is possible but this depends on the genetic cause - of which some are sporadic mutations and others are dominant. ...Read more
Femur length: Ultrasound imaging of the fetus can determine femur length with great accuracy. The normal relationship between the bones of the lower leg and femur is 1:1. If the femurs are short, either a constitutionally normally small fetus (frequently offspring of short parents), intrauterine growth restriction (iugr) or a skeletal dysplasia may exist. Normal short fetuses exhibit appropriate interval growth. ...Read more
Not necessarily.: Achondroplasia may be inherited as an autosomal dominant trait, meaning that getting the gene from 1 parent causes the child to have the disorder. If 1 parent has achondroplasia, the infant has a 50% chance of inheriting the disorder. If both parents have the condition, chances increase to 75%. However, most cases appear as spontaneous mutation, meaning 2 parents w/o it may have a child with it. ...Read more
