Abstract
BACKGROUND

Solitary rectal ulcer syndrome (SRUS) is a rare rectal disease with unknown etiology. Data on the genetic background in SRUS is lacking.

CASE SUMMARY

Here, we report the first case of SRUS in a mother-son relationship. Gene sequencing was conducted on the whole family, which revealed an inherited CHEK2 p.H371Y mutation. The experiment preliminarily revealed that the CHEK2 mutation did not affect the expression of CHEK2 protein, but affected the function of CHEK2, resulting in the expression level changes of downstream genes such as CDC25A.

CONCLUSION

SRUS is a genetic susceptibility disease where CHEK2 p.H371Y mutation may play a crucial role in the development and prognosis of SRUS.

Core Tip: Solitary rectal ulcer syndrome (SRUS) is a rare rectal disease with unknown etiology. Data on the genetic background in SRUS is lacking. Here, we present the first case of SRUS in a mother-son relationship. Gene sequencing and experiment preliminarily indicate that SRUS may serve as a genetic susceptibility disease in which CHEK2 p.H371Y mutation may play a crucial role in the development and prognosis of SRUS. This case may offer some new insights into the virulence genes and genetic background of SRUS.
