Recently, cases of dyschromatosis with SASH1 mutations have been reported worldwide; however, only one case has been reported from Japan. Here, we analyzed six Japanese patients who characteristically showed many lentigines on sun-exposed areas, using next-generation sequencing. We identified five novel heterozygous mutations in SASH1 (p.I586M, p.S531Y, p.R644W, p.T525R, and p.S516I) in our patients and their families. The p.R644W substitution identified in two unrelated families was the first mutation located in the sterile alpha motif 1 (SAM1) domain. The degree and location of the lentigines were variable across individuals, even if they shared the same SASH1 mutation. All mutations were predicted to be deleterious by six different algorithms used to evaluate the functional impact of a variation. In addition, immunohistopathological findings and RNA sequencing results suggested that SASH1 mutations were associated with an increase in the number of melanocytes, acceleration of melanogenesis, and upregulated hair keratin expression.NCS is defined as reduced or absent sensation in the chin and lower lip within the distribution of the mental or inferior alveolar nerves. Although commonly associated with local trauma, NCS can indicate an underlying malignancy or can be the presenting symptom of cancer recurrence. We describe a 6-year-old female patient with AML and t(8,21) who underwent allogeneic HCT. Five months post-HCT, the patient presented with right-sided facial pain and numbness in her chin and lower lip consistent with NCS. Two weeks later, the patient had bone marrow relapse indicating AML recurrence.
