Core Tip
Core Tip: Gathering data from different cases for the rare tetrasomy 18p chromosome abnormality disorder will facilitate mastering its genotype-phenotype relationship and diagnosis. This report described features for the first time for an Iranian patient. Compared to previously reported cases, this Iranian child displays a uniquely strong sense of smell, some less reported dysmorphic features and ten features generally reported. Her cytogenetic analyses revealed a small marker chromosome with a gain of 14Mb at the 18p arm. Apart from the usual clinical assessments, the non-invasive prenatal genetic testing is suggested to be used as a more accurate screening for detecting tetrasomy 18p.
