Reply to Letter to the Editor

Many thanks to Dr. Santos-Jasso for his Letter to the Editor in relation to our article. There were 10 syndromic patients in our series (trisomy 21 [n=3], congenital central hypoventilation syndrome [n=3], Mowat–Wilson syndrome [n=1], Jacobsen syndrome [n=1], Emmanuel syndrome [n=1], trisomy 8 [n=1]). Overall, 3/10 (30%) patients had a TZ length >5 cm compared with 8/38 (21%) in the nonsyndromic cases (p = 0.67), and therefore no statistically significant difference was observed between these groups.
