Her genetic testing did not identify pathogenic variants p.(Ala883Phe) and p.(Met918Thr) associated with MEN2B in exons 15 and 16 of the RET gene (NM_ 020975.4),1 or any pathogenic variants in exon 20 of the SOS1 gene (NM_ 005633.4), previously we found to be associated with mucosal neuroma syndrome and CNT.2 Here, RET is linked to multiple endocrine neoplasia type 2B.
