Abstract
Steroid-resistant nephrotic syndrome (SRNS) is a severe kidney disorder linked to over 60 genes, including NUP85, which plays a key role in nuclear pore function and glomerulogenesis. We identified a novel homozygous NUP85 variant (NM_024844.5: c.1379G > A, p.Arg460Gln) in a pediatric SRNS patient who also presented with cleft lip-palate and mild intellectual disability, marking the first reported association of these phenotypes with a NUP85 variant. Molecular dynamics simulations revealed that the variant destabilizes the protein's helix bundle, providing mechanistic insights into its potential pathogenic effects. This study broadens the known phenotypic spectrum of NUP85-related conditions and highlights the value of computational tools, such as molecular dynamics, in unraveling the impact of novel variants.
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
