Overlapping cortical malformations in patients with pathogenic variants in and .

Background: Malformations of cortical development (MCDs) have been reported in a subset of patients with pathogenic heterozygous variants in or , genes which encode for subunits of the N-methyl-D-aspartate receptor (NMDAR). The aim of this study was to further define the phenotypic spectrum of NMDAR-related MCDs.

Methods: We report the clinical, radiological and molecular features of 7 new patients and review data on 18 previously reported individuals with NMDAR-related MCDs.

The first two non-Finnish HYLS1 variants: Expanding the phenotypic spectrum of hydrolethalus syndrome.

Hydrolethalus syndrome (HLS) is a rare lethal fetal malformation disorder related to ciliogenesis disruption. This condition is more frequent in Finland where a founder missense variant in the HYLS1 gene was identified. No other HYLS1 variant has hitherto been implicated in HLS.

High-Density of FcγRIIIA (CD16) Tumor-Associated Neutrophils in Metastases Improves the Therapeutic Response of Cetuximab in Metastatic Colorectal Cancer Patients, Independently of the HLA-E/CD94-NKG2A Axis.

Antibody-dependent cellular cytotoxicity (ADCC) in the anti-tumor effect of cetuximab in metastatic colorectal cancer (mCRC) is only based on the impact of FcγRIIIA (CD16) polymorphisms as predictive of therapeutic response. However, nature, density and therapeutic impact of FcγRIIIA (CD16) effector cells in tumor remain poorly documented. Moreover, the inhibition of cetuximab-mediated ADCC induced by NK cells by the engagement of the new inhibitory CD94-NKG2A immune checkpoint has only been demonstrated .

Medicopsis romeroi nodular subcutaneous infection in a kidney transplant recipient.

Phaeohyphomycosis is a set of fungal infections caused by various dematiaceous fungi such as coelomycetes. These infections can occur either in immunocompetent or immunocompromised patients like solid organ transplants. Here we describe a nodular lesion of the right hallux that occurred in a kidney transplant patient.

Prospective evaluation of two screening methods for molecular testing of metastatic melanoma: Diagnostic performance of BRAF V600E immunohistochemistry and of a NRAS-BRAF fully automated real-time PCR-based assay.

Screening for theranostic biomarkers is mandatory for the therapeutic management of cutaneous melanoma. BRAF and NRAS genes must be tested in routine clinical practice. The methods used to identify these alterations must be sensitive to detect mutant alleles in a background of wild type alleles, and specific to identify the correct mutation.

Acanthosis nigricans, hypochondroplasia, and FGFR3 mutations: Findings with five new patients, and a review of the literature.

Early development of extensive acanthosis nigricans (AN) is a key feature in some patients who have hypochondroplasia (HCH) in association with FGFR3 mutations. We here report regarding five new patients with HCH who exhibited AN, and we compare their characteristics to the eight patients previously described in the literature. In these patients, the AN lesions began in childhood, and they were extensive.
