Abstract

Biallelic pathogenic variants in KLHL7 are known to result in Crisponi syndrome (CS)/cold-induced sweating syndrome type 1 (CISS1) like phenotype and Bohring-Opitz-like syndrome. In this report, a trio whole-exome sequencing (WES) was performed in proband with cold-induced sweating, microcephaly, facial dysmorphism, spasticity, failure to thrive, pigmentary abnormalities of the retina, hypoplasia of corpus callosum and periventricular nodular heterotopia. A novel homozygous in-frame deletion was identified in exon 2 of KLHL7, affecting the BTB domain of the protein. Our findings expand the clinical and molecular spectrum of KLHL7-related disorders.
