An Unusual Inheritance Pattern for Spinal Muscular Atrophy

Abstract: SUMMARY Progressive spinal muscular atrophy in infancy (Werdnig‐Hoffmann's Disease) is considered to be inherited as an autosomal recessive trait. This paper reports the occurrence of this process in first cousins which, in addition to other examples in the literature, suggests an alternate pattern of genetic transmission. Possible modes of inheritance are discussed, particularly that of a dominant inheritance requiring an allelomorphic activator gene for phenotypic expression.

“…However, several authors have described familial SMA affecting distant relatives, indicating a hereditary pattern incompatible with simple autosomal recessive inheritance (Brandt 1950, Wohlfart et a]. 1955, Kugelberg & Welander 1956, Becker 1964, Amick et al 1966, Almog & Tal 1968, Zellweger et al 1969, White & Blaw 1971, Zellweger et al 1972, Hausmanowa-Petrusewicz et al 1976, Zeiler et al 1976, Zerres & Grimm 1983. Becker (1964) analysed this mode of inheritance and postulated an allelic model.…”
