TUBGCP5 and congenital heart disease: There is only one such region of interest in our dataset: the 15q11.2 deletion involving the imprinted NIPA1, NIPA2, CYFIP1, and TUBGCP5 genes, which exhibit neurodevelopmental phenotypes, such as epilepsy, macrocephaly, and autism spectrum disorder, when inherited from the mother, while paternal deletions have been associated with congenital heart disease and abnormal muscle phenotypes [50].
