Bi-allelic TTI1 variants cause an autosomal-recessive neurodevelopmental disorder with microcephaly.

Telomere maintenance 2 (TELO2), Tel2 interacting protein 2 (TTI2), and Tel2 interacting protein 1 (TTI1) are the three components of the conserved Triple T (TTT) complex that modulates activity of phosphatidylinositol 3-kinase-related protein kinases (PIKKs), including mTOR, ATM, and ATR, by regulating the assembly of mTOR complex 1 (mTORC1). The TTT complex is essential for the expression, maturation, and stability of ATM and ATR in response to DNA damage. TELO2- and TTI2-related bi-allelic autosomal-recessive (AR) encephalopathies have been described in individuals with moderate to severe intellectual disability (ID), short stature, postnatal microcephaly, and a movement disorder (in the case of variants within TELO2).

A recurrent mutation in KCNA2 as a novel cause of hereditary spastic paraplegia and ataxia.

The hereditary spastic paraplegias (HSPs) are heterogeneous neurodegenerative disorders with over 50 known causative genes. We identified a recurrent mutation in KCNA2 (c.881G>A, p.

Adrenocortical carcinoma is a lynch syndrome-associated cancer.

Purpose: Adrenocortical carcinoma (ACC) is an endocrine malignancy with a poor prognosis. The association of adult-onset ACC with inherited cancer predisposition syndromes is poorly understood. Our study sought to define the prevalence of Lynch syndrome (LS) among patients with ACC.

Aging-related episodic memory decline: are emotions the key?

Episodic memory refers to the recollection of personal experiences that contain information on what has happened and also where and when these events took place. Episodic memory function is extremely sensitive to cerebral aging and neurodegerative diseases. We examined episodic memory performance with a novel test in young (N = 17, age: 21-45), middle-aged (N = 16, age: 48-62) and aged but otherwise healthy participants (N = 8, age: 71-83) along with measurements of trait and state anxiety.

Prevalence and type of BRCA mutations in Hispanics undergoing genetic cancer risk assessment in the southwestern United States: a report from the Clinical Cancer Genetics Community Research Network.

Purpose: To determine the prevalence and type of BRCA1 and BRCA2 (BRCA) mutations among Hispanics in the Southwestern United States and their potential impact on genetic cancer risk assessment (GCRA).

Patients And Methods: Hispanics (n = 746) with a personal or family history of breast and/or ovarian cancer were enrolled in an institutional review board-approved registry and received GCRA and BRCA testing within a consortium of 14 clinics. Population-based Hispanic breast cancer cases (n = 492) enrolled in the Northern California Breast Cancer Family Registry, negative by sequencing for BRCA mutations, were analyzed for the presence of the BRCA1 ex9-12del large rearrangement.

Why is everyone so anxious?: an exploration of stress and anxiety in genetic counseling graduate students.

Stress is an inevitable part of daily life. Studies of graduate student stress exist, but none include genetic counseling students. The present mixed-methods study investigated 225 genetic counseling students' stress and anxiety levels using the State-Trait Anxiety Inventory (STAI; Spielberger et al.

Induction and measurement of episodic memories in healthy adults.

Episodic memory is that part of our memory which enables us to memorize a personal event (what) in terms of place (where) and time (when). It is expressed on verbal and behavioral level. In this report we describe a novel method to induce de novo episodic memories in humans for unique events in the laboratory and measure them with standardized ratings and non-verbal motor responses.
