Novel genotypes and phenotypes among Chinese patients with Floating-Harbor syndrome.

ABSTRACT:

Background

Floating-Harbor syndrome (FHS) is a rare syndromic short stature disorder caused by truncating variants in SRCAP. Few Chinese FHS patients had been reported so far and limited knowledge regarding the benefit of growth hormone treatment existed.

Methods

We ascertained 12 short stature patients with molecularly confirmed diagnosis of FHS by whole exome sequencing. We performed a comprehensive clinical evaluation for all patients and assessed the responsiveness of growth hormone treatment in a subset of the patients.

Results

Five distinct pathogenic/likely pathogenic variants were identified in 12 independent FHS patients including two previously reported variants (c.7303C > T/p.Arg2435Ter and c.7330C > T/p.Arg2444Ter) and three novel variants (c.7189G > T/p.G
