We examined the deletion of the survival motor neuron [SMN] and neuronal apoptosis inhibitory protein [NAIP]genes in patients with spinal muscular atrophy [SMA] using polymerase chain reaction followed by restriction site assay methods. The study included 16 Saudi patients [9 SMA type I and 7 SMA type II]and 6 healthy Saudi volunteers. The homozygous deletions of exons 7 and 8 of the telomeric SMN gene, and exon 5 of the NAIP gene were found in all SMA type I patients. Exons 7 and 8 of telomeric SMN were deleted in all SMA type II patients. However, exon 5 of NAIP was deleted in three of the seven cases. All control volunteers and all family members of the patients had normal SMN and NAIP. The incidence of NAIP deletion was higher in the more severe SMA cases and the dual deletion of the SMN and NAIP genes was more common in Saudi SMA type I patients compared with patients of other ethnic groups

Molecular Analysis of Survival Motor Neuron and Neuronal Apoptosis Inhibitory Protein Genes in Macedonian Spinal Muscular Atrophy PatientsSpinal muscular atrophy (SMA) is classified according to the age of onset and severity of the clinical manifestations into: acute (Werding-Hoffman disease or type I), intermediate (type II) and juvenile (Kugelberg-Wilander disease or type III) forms. All three SMAs have been linked to markers at 5q11.2-q13.3. Two candidate genes deleted in SMA patients are the survival motor neuron (SMN) gene and the neuronal apoptosis inhibitory protein (NAIP) gene. We have performed molecular analyses of these genes in 30 unrelated Macedonian families (17 with type I, eight with type II and five with type III forms of the disease). Deletions of exons 7 and 8 of the SMN gene were found in 76.6% (23/30) of patients (94.1% in type I, 87.5% in type II). Among these 23 families, 19 had both exons deleted, while four had deletions only of exon 7. Deletions of exon 5 of the NAIP gene were found in 41.2% (7/17) patients with type I SMA and in 12.5% (1/8) of patients with type II SMA. No deletions of the SMN gene were found in 30 parents and 30 normal controls. We found 2/30 (6.7%) parents to be homozygous for the deletion of exon 5. Our data support the hypothesis that the telomeric SMN gene plays a major role in determining the clinical course of the disease, while the defects in the NAIP gene have only a modifying effect on the phenotype.

Spinal muscular atrophy (SMA) is an autosomal recessive neuromuscular disorder caused by mutations of the SMN1 gene. It is characterized by significant phenotype variability. In this study, we analyzed possible phenotype modifiers of the disease - the size of the deletion in the SMA region, the number of SMN2 gene copies, as well as the effect of gender. Among the factors analyzed, two seem to influence the SMA phenotype: the number of SMN2 gene copies and a deletion in the NAIP gene. A higher number of SMN2 copies makes the clinical symptoms more benign, and the NAIP gene deletion is associated with a more severe phenotype. The influence of gender remains unclear. In a group of 1039 patients, 55% of whom were male, the greatest disproportion was in the SMA1 (F/M = 0.78) and SMA3b (F/M = 0.45) forms. In SMA1 a deletion in the NAIP gene was seen twice as frequently in girls compared to boys. In three patients, we observed genotypes atypical for the chronic forms of SMA: two patients with SMA3a and 3b had a deletion of the NAIP gene, and a third patient with SMA2 had one copy of the SMN2 gene.

Naip Gene

The neuronal apoptosis inhibitory protein (NAIP) gene, also known as the baculovirus inhibitor of apoptosis repeat-containing protein 1 (BIRC1) gene, is a member of the inhibitors of apoptosis (IAP) family and was first characterized as a candidate gene for spinal muscular atrophy (SMA). The expression of NAIP has been thoroughly studied in the central nervous system and overlaps the pattern of neurodegeneration in SMA. Recent studies have pointed to a role for NAIP in non-neuronal cells. We report here the production of a specific anti-NAIP antibody and the profile of NAIP expression in human adult tissues by Western blot and immunohistochemical detection methods. NAIP was detected in a number of tissues by Western blot analysis, but immunohistochemistry revealed that NAIP's presence in certain tissues, such as liver, lung, and spleen, is most likely due to macrophage infiltration. In the small intestine, the expression of NAIP coincides with the expression of p21WAF1. This observation, coupled with findings from other groups, suggests a role for NAIP in increasing the survival of cells undergoing terminal differentiation as well as the possibility that the protein serves as an intestinal pathogen recognition protein.
