ABSTRACT:
Neurofibromatosis type I (NF1) (OMIM, 162200) and Legius
syndrome (OMIM, 611431) both have multiple café au lait spots. It is a challenge
to differentiate the two diseases. Here we report a Legius syndrome-like
patient who finally was identified as NF1 with a novel mutation in NF1 exon1 (c.55G > T). The mutation
caused a substitution of a glutamic acid (GAG) with a terminator codon (TAG). For those patients with only
multiple café au lait macules, axillary and inguinal freckling, but
without any other clinical signs in NF1 and Legius syndrome, a gene testing is
necessary to give a final diagnose. We suggested to use “Neurofibromatosis
type 1—like syndrome”
to describe those patients just like our patient reported here.
