Novel mutation in gene associated with congenital hypertrichosis and acromegaloid facial features, without cardiac or skeletal anomalies: a new phenotype.

INTRODUCTION

Mutations in are associated with Cantú syndrome (CS), a very rare genetic disorder characterized by congenital hypertrichosis, acromegaloid facial appearance (AFA), cardiomegaly, and skeletal anomalies.

CASE REPORT

We report an 8-year-old female patient with congenital generalized hypertrichosis and coarse facial appearance but without cardiovascular or skeletal compromise. Whole exome sequencing revealed a novel de novo heterozygous mutation in . In addition, the genotype and phenotype of the patient were compared with those of the patients reported in the literature and with other related conditions that include AFA, hypertrichosis and AFA, and CS.

CONCLUSION

This is the first report of a South-American patient with mutation in . We propose that her phenotype is a part of a spectrum of features associated with congenital hypertrichosis and mutations in , which differs from CS and related disorders. Whole exome sequencing enabled the identification of the causality of this disease characterized by high clinical and genetic heterogeneity.
