Interstitial deletion of the short arm of chromosome 12. Report of a new patient and review of the literature.
In this report we describe a female neonate with 12p interstitial deletion (karyotype: 46,XX,del(12)(pter----p13.1::p11.2----cen----qter). In addition to severe psychomotor retardation, facial dysmorphism and Turner like stigmata, she presented marked hypoplasia of the external genitalia and right heart hypoplasia. Study of LDH activity showed a marked decrease of LDHB activity contrasting with an elevated LDHA.
