Objective: To detect gene mutation in proband and his mother from a family with piebaldism.
Methods: Diagnosis of a patient with piebaldism was validated by pathology, ultrastructural examination and the typical clinical manifestation. PCR and DNA sequencing were carried out to detect gene mutation of a family with piebaldism.
Results: G1833A transition in the KIT gene was found in the proband of the family with piebaldism. This mutation resulted in V604I substitution in KIT gene. No mutation was found in 100 normal individuals and other family members.
Conclusion: The mutation of V604I is the cause of clinical phenotype of the family with piebaldism.

Here, we present a protocol to alter the production of alternatively spliced mRNA variants, without affecting the overall gene expression, through CRISPR-Cas9-engineered genomic mutations in mice. We describe steps for designing guide RNA to direct Cas9 endonuclease to consensus splice sites, producing transgenic mice through pronuclear injection, and screening for desired mutations in cultured mammalian cells using a minigene splicing reporter. Splice isoform-specific mouse mutants provide valuable tools for genetic analyses beyond loss-of-function and transgenic alleles.

Biomolecular condensates are dynamic membraneless compartments that regulate a myriad of cellular functions. A particular type of physiological condensate called stress granules (SGs) has gained increasing interest due to its role in the cellular stress response and various diseases. SGs, composed of several hundred RNA-binding proteins, form transiently in response to stress to protect mRNAs from translation and disassemble when the stress subsides.

A common digestive system cancer with a dismal prognosis and a high death rate globally is breast cancer (BRCA). BRCA recurrence, metastasis, and medication resistance are all significantly impacted by cancer stem cells (CSCs). However, the relationship between CSCs and the tumor microenvironment in BRCA individuals remains unknown, and this information is critically needed.

Purpose: Age stratification influences the clinicopathological features and survival outcomes of breast cancer. We aimed to understand the effect of age on gene variants in young Chinese women with breast cancer compared with those from The Cancer Genome Atlas (TCGA).
Methods: Enrolled patients ≤ 40 years old (N = 370) underwent germline or somatic genetic testing using a 32-gene hereditary cancer panel at Fujian Union Hospital.

The Streptococcus canis Cas9 protein (ScCas9) recognizes the NNG protospacer adjacent motif (PAM), offering a wider range of targets than that offered by the commonly used S. pyogenes Cas9 protein (SpCas9). However, both ScCas9 and its evolved Sc++ variant still exhibit low genome editing efficiency in plants, particularly at the less preferred NTG and NCG PAM targets.
