GeneDx RCV000157973 SCV000207908 pathogenic not provided 2016-06-29 criteria provided, single submitter clinical testing c.864+2 T>C: IVS6+2 T>C in intron 6 of the LAMP2 gene (NM_002294.2). Although c.864+2 T>C in the LAMP2 gene has not been reported previously as a disease-causing mutation, this mutation destroys the canonical splice donor site in intron 6 and is predicted to cause abnormal gene splicing. This mutation is expected to lead to either an abnormal message, which is subjected to nonsense-mediated mRNA decay, or to an abnormal protein product if the message is used for protein translation. Additionally, c.864+2 T>C was not observed in approximately 6500 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, indicating it is not a common benign variant in these populations.Other splice site mutations in the LAMP2 gene have been reported in association with Danon disease in males and LAMP2-related cardiomyopathy in females (Horvath J, 2003). In summary, c.864+2 T>C in the LAMP2 gene is interpreted as a disease-causing mutation. The variant is found in HCM,CARDIOMYOPATHY panel(s).
