Evidence for haploinsufficiency phenotype
PubMed ID Description
25363768 Iossifov I et al. sequenced exomes from 2,508 children with autistic spectrum disorder (ASD), 1,911 unaffected siblings and the parents of each family. Exome data were analyzed by 3 different institutes. They measured de novo rates in quad families (one affected and one unaffected child) over genomic positions at which all family members had ?40? sequence coverage. There were 2 de novo gene-disrupting variants in TCF7L2 were detected in 2 different probands (ASD, non-verbal IQ <90) from different families, both of these two variants were on splice-site.
