Abstract

Focal facial dermal dysplasia (FFDD) type IV is a rare inherited facial defect caused by biallelic variants in CYP26C1. This study reports two novel Belgian FFDD type IV cases, both homozygous for a recurrent CYP26C1 frameshift variant, with a common 700 kb haplotype, indicating a founder effect.

在比利时人群中，局灶性面部皮肤发育不良（FFDD） IV型的意外高患病率与奠基者效应有关。

局灶性面部真皮发育不良（FFDD） IV型是一种罕见的遗传性面部缺陷，由CYP26C1双等位基因变异引起。本研究报告了两例新的比利时FFDD IV型病例，均为复发性CYP26C1移码变体纯合，具有共同的700 kb单倍型，表明建立者效应。

期刊介绍： Clinical Genetics links research to the clinic, translating advances in our understanding of the molecular basis of genetic disease for the practising clinical geneticist. The journal publishes high quality research papers, short reports, reviews and mini-reviews that connect medical genetics research with clinical practice. Topics of particular interest are: • Linking genetic variations to disease • Genome rearrangements and disease • Epigenetics and disease • The translation of genotype to phenotype • Genetics of complex disease • Management/intervention of genetic diseases • Novel therapies for genetic diseases • Developmental biology, as it relates to clinical genetics • Social science research on the psychological and behavioural aspects of living with or being at risk of genetic disease
