Abstract

Abstract Background Congenital insensitivity to pain (CIP) is a rare autosomal recessive syndrome characterized by lack of pain perception with a wide spectrum of clinical signs such as anosmia and hyposmia. SCN9A gene variants were found to be associated with CIP. We here report on a family with three CIP affected patients referred for genetic investigations. Methods and Results Whole exome sequencing analysis revealed the presence of a novel nonsense, homozygous SCN9A pathogenic variant: SCN9A (NM_001365536.1): c.4633G > T, p.(Glu1545*) in exon 26. Conclusion Our three Lebanese patients had CIP, urinary incontinence and normal olfactory function while two of them also presented with osteoporosis and osteoarthritis; this association of features has not been previously reported in the literature. We hope that this report would contribute to a better delineation of the spectrum caused by SCN9A pathogenic variants.
