Attention to faces in social context in children with neurofibromatosis type 1

Abstract: Children with neurofibromatosis type 1 (NF1) demonstrated atypical gaze behaviour when attending to faces. NF1 gaze behaviour was characterized by normal initial fixation on faces but shorter face dwell time. Decreased attention to faces was associated with elevated autism traits in the sample with NF1.

“…7 While there has been some speculation that cognitive impairments may explain the behavioural and social problems that children with NF1 experience, 6 our data indicate only weak relationships between general intellectual functioning and autism traits on the SRS-2, and no relationship between IQ and social skills on the SSIS-RS. This is not dissimilar to evidence from the literature on idiopathic ASD, which suggests a complicated, non-linear relationship between autism traits, IQ, and adaptive functioning, 30 as well as NF1-specific literature that indicates minimal-to-no relationships between IQ and social attention skills, 31 facial emotion recognition, theory of mind, and ASD symptomatology. 2 Ultimately, the weak relationships between IQ and SRS-2 and SSIS-RS in the current study suggest these questionnaires are not simply measuring general cognitive deficits in NF1, but a fairly unrelated social-behavioural phenotype.…”

“…In the example of social visual engagement, while nearly all children affected by autism exhibit significant atypicalities, a small proportion of unaffected infants in the general population exhibited the same atypicalities (44), suggesting that such deficits may be necessary but not sufficient to cause clinical autistic syndromes, and may be genetically independent from other components of inherited risk. A pilot eye-tracking study of individual children representing a diverse set of loss-of-function mutations in NF1—a recently-recognized quantitative trait locus for autistic impairment (58,59)—made precisely this observation: that decreased attention to faces was associated with elevated autism traits in the affected children, even though many controls had comparably low attention to faces.…”
