ABSTRACT
We describe two unrelated Indian boys with Mental retardation with language impairment with or without autistic features (OMIM#613670). Novel pathogenic variants c. 593_599 delins AGAAG and c.1556T>C in FOXP1 were identified in Patients 1 and 2, respectively by exome sequencing. The patients shared the cardinal features of significant language impairment, prominent forehead, downslanted palpebral fissures, frontal upsweep of hair, and behavioral abnormalities. Camptodactyly (with pterygia in Patient 2) was an additional feature noted in our study. The phenotype was consistent with previous reports of patients with monogenic defects in FOXP1. The facial features overlap with Sotos syndrome. However, presence of frontal upsweep of hair is a good pointer toward FOXP1 related syndromic intellectual disability.
