Targeted syndrome/gene under study:

Gene: KIAA1109 – MIM 611565 ; Disorder: Alkuraya-Kucinskas syndrome – MIM 617822


We have recently encountered an individual with bi-allelic variants in BLTP1 (also known as KIAA1109) , corresponding to a diagnosis of Alkuraya-Kucinskas syndrome. He presented with a particularly interesting brain MRI. We are looking for additional affected individuals, preferably individuals who have had brain imaging, in order to further delineate the phenotype of this syndrome.
