Watkins and Zimmer Syndrome

Watkins and Zimmer Syndromes are two extremely rare genetic conditions both occurring due to a mutation of the chromosome 13, neither of the two conditions have been associated with mental retardation which is typically common in other conditions such as Down syndrome.
Watkins Syndrome is caused by a loss of function of the chromosomes' paternal functions, while Zimmer's is caused by a loss of function of the maternal functions. Both syndromes are associated with Dyspolia.
