Abstract
3p25 deletion syndrome is characterized by mental retardation, growth retardation, hypotonia, microcephaly, ptosis, and micrognathia. Of the 42 persons with this deletion syndrome cited in the literature, only 2 patients, a mother-daughter pair, have previously been reported without apparent clinical consequence. We present a second mother-daughter dyad with a terminal 3p25.3-3pter deletion, who present with only mild clinical effects. In addition to cytogenetic analysis, array CGH was performed to determine the breakpoints at the molecular level. Our data show that the 3p25 deletion syndrome may, therefore, reflect a much broader phenotypic spectrum than previously recognized.
