Goldberg-Shprintzen Syndrome Associated with a Novel Variant in the KIFBP Gene.


ABSTRACT: Goldberg-Shprintzen syndrome (GOSHS) is characterized by microcephaly, developmental delay, dysmorphic features, Hirschsprung disease (HSCR), and brain anomalies. The kinesin family binding protein (KIFBP; MIM 60937) gene has been identified as the responsible gene of the syndrome. To date, 16 different biallelic KIFBP mutations have been identified in 34 patients with GOSHS. Even though most of these mutations are nonsense and frameshift, 3 missense mutations have also been described. Here, we report an 18-month-old patient with microcephaly, developmental delay, dysmorphic features and HSCR. Exome analysis was performed to clarify the etiology of the clinical features. A previously unreported homozygous c.1723delC (p.H575Ifs*19) variant was detected in the last exon 7 of KIFBP which led to GOSHS. According to our findings, we suggest that this mutation expands mutational databases and contributes to the understanding of the phenotypic features of the syndrome.
