Abstract
HnRNPs are ubiquitously expressed RNA-binding proteins, tightly controlling posttranscriptional gene regulation. Consequently, hnRNP networks are essential for cellular homeostasis and their dysregulation is associated with cancer and other diseases. However, the physiological function of hnRNPs in non-cancerous cell systems are poorly understood. We analyzed the importance of HNRNPDL in endothelial cell functions. Knockdown of HNRNPDL led to impaired proliferation, migration and sprouting of spheroids. Transcriptome analysis identified cyclin D1 (CCND1) and tropomyosin 4 (TPM4) as targets of HNRNPDL, reflecting the phenotypic changes after knockdown. Our findings underline the importance of HNRNPDL for the homeostasis of physiological processes in endothelial cells.

Abstract
Bi-allelic variants in VWA1, encoding Von Willebrand Factor A domain containing 1 protein localized to the extracellular matrix (ECM), were linked to a neuromuscular disorder with manifestation in child- or adulthood. Clinical findings indicate a neuromyopathy presenting with muscle weakness. Given that pathophysiological processes are still incompletely understood, and biomarkers are still missing, we aimed to identify blood biomarkers of pathophysiological relevance: white blood cells (WBC) and plasma derived from six VWA1-patients were investigated by proteomics. Four proteins, BET1, HNRNPDL, NEFM and PHGDH, known to be involved in neurological diseases and dysregulated in WBC were further validated by muscle-immunostainings unravelling HNRNPDL as a protein showing differences between VWA1-patients, healthy controls and patients suffering from neurogenic muscular atrophy and BICD2-related neuromyopathy. Immunostaining studies of PHGDH indicate its involvement in apoptotic processes via co-localisation with caspase-3. NEFM showed an increase in cells within the ECM in biopsies of all patients studied. Plasma proteomics unravelled dysregulation of 15 proteins serving as biomarker candidates among which a profound proportion of increased ones (6/11) are mostly related to antioxidative processes and have even partially been described as blood biomarkers for other entities of neuromuscular disorders before. CRP elevated in plasma also showed an increase in the extracellular space of VWA1-mutant muscle. Results of our combined studies for the first time describe pathophysiologically relevant biomarkers for VWA1-related neuromyopathy and suggest that VWA1-patient derived blood might hold the potential to study disease processes of clinical relevance, an important aspect for further preclinical studies.

Abstract
Limb girdle muscular dystrophy is a genetically inherited condition that primarily affects skeletal muscle leading to progressive, predominantly proximal muscle weakness at presentation. Autosomal dominant LGMD represent 10% of all LGMDs. HNRNPDL-related muscular dystrophy, LGMD1G/LGMD D3 (MIM#609115), is an extremely rare autosomal dominant adult onset myopathy described in a handful of families. Here we fully characterized the muscular and respiratory involvement of a 58 years old Italian woman presenting the previously reported pathogenic variant c.1132G > C p.(Asp378Asn) in the HNRNPDL gene.

Abstract
Limb-girdle muscular dystrophies (LGMD) are a group of clinically and genetically heterogeneous diseases characterized by weakness and wasting of the pelvic and shoulder girdle muscles. Twenty-four recessive LGMD (types R1-R24) and five dominant LGMD (types D1-D5) have been identified with characterization of mutations in various genes. To date, LGMD D3 (previously known as LGMD1G) has been characterized in only two families with Brazilian or Uruguayan origin. Each was caused by a distinct mutation at codon 378 in the prion-like domain of HNRNPDL encoding heterogeneous nuclear ribonucleoprotein D like (HNRNPDL), an RNA processing protein. Our study characterized eight patients suffering from LGMD D3 in a Chinese family spanning three generations. Muscle biopsy specimens from two patients showed a myopathy with rimmed vacuoles. Sequencing analysis revealed a heterozygous c.1132G > A (p.D378N) mutation in HNRNPDL that co-segregated with disease phenotype in the family. The same mutation has been identified previously in the Brazilian family with LGMD D3. However, most patients in the current family showed distal as well as proximal limb weakness rather than weakness of toe and finger flexor muscles that were typical features in the other two LGMD D3 families reported previously. The present study indicates that the same mutation in HNRNPDL results in various phenotypes of LGMD D3. That all mutations in three unrelated families with different ethnic background occur at the same position in codon 378 of HNRNPDL gene suggests a mutation hotspot. Acceleration of intrinsic self-aggregation of HNRNPDL caused by mutation of the prior-like domain may contribute to the pathogenesis of the disease.

Abstract
4q21 microdeletion syndrome (MIM: 613509) is a new genomic disorder characterized by intellectual disability, absent or severely delayed speech, growth retardation, hypotonia, variable brain malformation, and facial dysmorphism. The critical genes had been proposed based on an overlapping 1.37 Mb genomic region. No further refinement has been done since year 2010. Here, we present three cases with 4q21 deletion identified by clinical chromosomal microarray analysis. One of the cases have a de novo 761 kb deletion which is the smallest deletion ever reported at this locus. It provides an opportunity to further define the critical regions/genes associated with specific features of the 4q21 microdeletion syndrome. The evidence support the notion that PRKG2 and RASGEF1B are critical genes for intellectual disability and speech defect, and the heterogeneous nuclear ribonucleoprotein HNRNPD and HNRNPDL (previously known as HNRPDL) genes are associated with growth retardation and hypotonia. © 2016 Wiley Periodicals, Inc.
