Absolutely loved this! For the last 6 months I have been reviewing genetic testing cases for an insurance company. I've been doing a lot of self education on each case/syndrome, but this helped me put more of the pieces together. Thanks!

You are very welcome! Thank you very much for your kind note.

PWS is caused by lack of the paternal segment 15q11.2-q12. Basically, there are 2 mechanisms by which such a loss can occur: either through deletion of just the paternal 'critical' segment or through loss of the entire paternal chromosome 15 with presence of 2 maternal homologs (uniparental maternal disomy)

excellent tutorial, thanks. I actually lost two female child at individual occasions. We have done kareotype of 2nd and it appeared normal. Should we done kareotype of me and my wife? My both child were affected with hypotonia from birth and did not able to breath properly. Any other test you suggest that can tell which copy can affect child, i.e. from mother or father?

[@pediatricboardalastminuter1892]

I am really sorry about your loss, It is really important to know more details in order to understand the problem, for example, if any abnormal facial features or structural abnormalities suggesting syndromic cause, was the hypotonia peripheral or central?, at what age they died. Genetic testing can be helpful, but the most important to know what you are looking for, simple karyotype may not detect many genetic diseases, sometime you may need microarray, also not all causes of hypotonia are genetic.

[@pediatricboardalastminuter1892]

Thanks.

[@dhaval2021]

thank you so much for the comment, it will really help us for the future child planning. First one died after 4 days and 2nd after 8, both babies had very rare movement. As per doctor reason for death was respiratory failure because of muscle weakness. After removing ventilator babies were unable to breath, It wasn't because of prematurity but because of muscle weakness. can you please let me know what other causes of hypotonia? Reason is our kareotype report came yesterday and it's negetive. means nothing unusual has been detected.

[@pediatricboardalastminuter1892]

SMA type I - Acute infantile or Werdnig-Hoffman diseasePatients present before 6 months of age, with 95% of patients having signs and symptoms by 3 months. They have severe, progressive muscle weakness and flaccid or reduced muscle tone (hypotonia). Bulbar dysfunction includes poor suck ability, reduced swallowing, and respiratory failure. Patients have no involvement of the extraocular muscles, and facial weakness is often minimal or absent. They have no evidence of cerebral involvement, and infants appear alert. Reports of impaired fetal movements are observed in 30% of cases, and 60% of infants with SMA type I are floppy babies at birth. Prolonged cyanosis may be noted at delivery. In some instances, the disease can cause fulminant weakness in the first few days of life. Such severe weakness and early bulbar dysfunction are associated with short life expectancy, with a mean survival of 5.9 months. In 95% of cases, infants die from complications of the disease by 18 months.

[@pediatricboardalastminuter1892]

Spinal Muscular Atrophy or SMA is one of the causes

Is the video useful for studying pathology of third year of medical?

[@pediatricboardalastminuter1892]

I do not think these lecture will help you in the third year pathology. Its focused more on general pediatrics. Thanks.

[@doctorromy1]

thanks very much doctor Osama, let me ask you if this book and series could help me passing Arab board exam ?

[@pediatricboardalastminuter1892]

+doctorromy1 Thank you for your inquiry, I do not have any information about the Arab Board examination. This book originally designed for the pediatrician who are trying to pass and studying for the American Pediatric Board examination. The best is to ask the people who already passed the Arab Board exam and their experience for the best resources.
