BACKGROUND/OBJECTIVES: Deletions on the short arm of chromosome 2 at bands p11 and p12 have been detected in association with short stature, mild mental retardation and speech delay.
RESULTS: We describe a 4 year-old boy with some facial dysmorphic traits, congenital malformations and pre- and post-natal growth failure. He also presented marked expressive language problems. The molecular karyotype revealed a 108 Kb deletion within the seventh intron of the CTNNA2 gene at 2p11.2-p12. We observed that some features (short stature, facial dysmorphisms and speech delay) were present in our patient and in patients carrying much larger overlapping deletions.
CONCLUSIONS: The description of this small intragenic rearrangement might help to elucidate the role of the single genes included in the 2p11.2-p12 critical region.
