Severe combined immune deficiency (SCID) is a group of genetically heterogeneous diseases caused by an early block in T cell differentiation and present with life threatening infections, often within the first year of life. Janus kinase (JAK)3 gene mutations have been found to cause autosomal recessive T-B+ SCID phenotype. In this study we describe three patients with a novel deep intronic mis-splicing mutation in JAK3 as a cause of T-B+NK- SCID highlighting the need for careful evaluation of intronic regulatory elements of known genes associated with clearly defined clinical phenotypes. We present the cases and discuss the current literature.

Whole genome sequencing completes the molecular genetic testing workflow of patients with Lynch syndrome.

Multigene panel tests (MGPTs) revolutionized the diagnosis of Lynch syndrome (LS), however noncoding pathogenic variants (PVs) can only be detected by complementary methods including whole genome sequencing (WGS). Here we present a DNA-, RNA- and tumor tissue-based WGS prioritization workflow for patients with a suspicion of LS where MGPT detected no LS-related PV. Among the 100 enrolled patients, MGPT detected 28 simple PVs and an additional 3 complex PVs.

In 2021, the Indian Undiagnosed Diseases Program was initiated for patients without a definite diagnosis despite extensive evaluation in four participating sites. Between February 2021 and March 2023, a total of 88 patients were recruited and underwent deep phenotyping. A uniform methodology for data re-analysis was implemented as the first step prior to conducting additional genomic testing.

Complex deep learning models trained on very large datasets have become key enabling tools for current research in natural language processing and computer vision. By providing pre-trained models that can be fine-tuned for specific applications, they enable researchers to create accurate models with minimal effort and computational resources. Large scale genomics deep learning models come in two flavors: the first are large language models of DNA sequences trained in a self-supervised fashion, similar to the corresponding natural language models; the second are supervised learning models that leverage large scale genomics datasets from ENCODE and other sources.

Genomic variants causing abnormal splicing play important roles in genetic disorders and cancer development. Among them, variants that cause the formation of novel splice-sites (splice-site creating variants, SSCVs) are particularly difficult to identify and often overlooked in genomic studies. Additionally, these SSCVs are frequently considered promising candidates for treatment with splice-switching antisense oligonucleotides (ASOs).

Constitutional variants in the RB1 gene predispose individuals to the development of Retinoblastoma (RB) and the occurrence of second tumors in adulthood. Detection of causal RB1 gene variants is essential to establish the genetic diagnosis and to performing familial studies and counseling. In our cohort of 579 Spanish RB patients, 15% of cases suspected to have a genetic origin remained negative after traditional Sanger sequencing and Multiplex Ligation-dependent Probe Amplification (MLPA) of RB1 gene, likely due to the possibility of mosaicism or non-coding variants.
