Culture-Free Whole Genome Sequencing of Using Ligand-Mediated Bead Enrichment Method.

Background: Direct whole genome sequencing (WGS) of () can be used as a tool to study drug resistance, mixed infections, and within-host diversity. However, WGS is challenging to obtain from clinical samples due to low number of bacilli against a high background.

Methods: We prospectively collected 34 samples (sputum, n = 17; bronchoalveolar lavage, n = 13; and pus, n = 4) from patients with active tuberculosis (TB).

Molecular effects of indoor tanning.

Background: Tanning bed users have a significantly increased risk of melanoma, but it remains unclear how indoor tanning drives melanomagenesis. Tanning bed radiation is often thought of as a substitute for natural UV radiation despite differences in the maximum doses, UV content, body sites exposed, and patterns of melanoma that arise.

Methods: To better understand the epidemiologic trends and etiology of melanoma associated with tanning bed use, we described the patterns of melanoma in patients with quantifiable tanning bed usage and performed exome sequencing of 182 melanocytes from normal skin of a subset of these patients.

A Novel LINS1 Truncating Mutation in Autosomal Recessive Nonsyndromic Intellectual Disability.

The large majority of cases with intellectual disability are syndromic (i.e. occur with other well-defined clinical phenotypes) and have been studied extensively.

A Novel Missense Variant in PHF6 Gene Causing Börjeson-Forssman-Lehman Syndrome.

Börjeson-Forssman-Lehman Syndrome (BFLS) is a rare X-linked recessive syndrome characterized by intellectual disability, developmental delay, obesity, epilepsy, swelling of the subcutaneous tissues of the face, large but not deformed ears, hypogonadism, and gynecomastia. Pathogenic mutations in PHD finger protein 6 (PHF6) have been reported to cause BFLS. In this study, we describe two male siblings with mild intellectual disability, global developmental delay, short stature, microcephaly, and nyctalopia.

A Novel Splice Site Mutation in in Patients With Primary Immunodeficiency Exhibiting Susceptibility to Mycobacterial Diseases.

Primary immunodeficiency (PID) refers to a group of heterogeneous genetic disorders with a weakened immune system. Mendelian susceptibility to mycobacterial disease (MSMD) is a subset of PID in which patients exhibit defects in intrinsic and innate immunity. It is a rare congenital disorder characterized by severe and recurrent infections caused by weakly virulent mycobacteria or other environmental mycobacteria.

Family-Based Next-Generation Sequencing Study Identifies an Variant in an Infant with Primary Immunodeficiency.

Primary immunodeficiencies (PIDs) are a rare and heterogeneous group of inherited genetic disorders that are characterized by an absent or impaired immune system. In this report, we describe the use of next-generation sequencing to investigate a male infant with clinical and immunological manifestations suggestive of a PID. Whole-exome sequencing of the infant along with his parents revealed a novel nucleotide variant (cytosine to adenine substitution at nucleotide position 252) in the coding region of the interleukin 2 receptor subunit gamma () gene.

Exome sequencing reveals a novel splice site variant in HUWE1 gene in patients with suspected Say-Meyer syndrome.

Say-Meyer syndrome is a rare and clinically heterogeneous syndrome characterized by trigonocephaly, short stature, developmental delay and hypotelorism. Nine patients with this syndrome have been reported thus far although no causative gene has yet been identified. Here, we report two siblings with clinical phenotypes of Say-Meyer syndrome with moderate to severe intellectual disability and autism spectrum disorder.
