Locus FRA7A ZNF713

A spectrum of developmental disorders that includes autism, and Asperger syndrome. Signs and symptoms include poor communication skills, defective social interactions, and repetitive behaviors¹.

Prevalence

1 proband reported alongside 3 individuals with premutations, found in 2 families without discussion of ancestry/ethnicity².

Age of Onset

2-3 (four individuals)².

Details

176 controls were used to establish the benign range (5-22 repeats), whereas a singular proband was identified with ~450 repeats². The observed intermediate alleles were presumed to function as premutations, with variable amounts of methylation².

Mechanism

LoF

Methylation, evidence of transcriptional misregulation^3,2.
