Purple butter clam (Saxidomus purpuratus) is an economically important bivalve shellfish. This species belongs to the subclass Heterodonta that diverged in calcite seas with low magnesium concentrations. We sequenced and assembled its genome and performed an evolutionary comparative analysis. A total of 911 Mb assembly of S. purpuratus was anchored into 19 chromosomes and a total of 48,090 protein-coding genes were predicted. We identified its repeat-based expanded genes that are associated with the sodium/potassium-exchange ATPase complex. In addition, different types of ion transporters were enriched in the common ancestor of Heterodonta (calcium, sulfate, and lipid transporters) and the specific evolution of S. purpuratus (calcium and sodium transporters). These differences seem to be related to the divergence times of Heterodonta (calcitic sea) and Veneraidea (aragonitic sea). Furthermore, we analyzed the evolution of scavenger receptor (SR) proteins in S. purpuratus, which are involved in a wide range of immune responses, and compared them to the closely related Cyclina sinensis. We showed that a small number of SR proteins, exhibited collinearity between the two genomes, which is indicative of independent gene evolution. Our genomic study provides an evolutionary perspective on the genetic diversity of bivalves and their adaptation to historical changes in the marine environment.

Transient Hypoparathyroidism

Minagawa M, Yasuda T, Kobayashi Y, Niimi H. Transient pseudohypoparathyroidism of the neonate. Eur J Endocrinol 1995:133:151–5. ISSN 0804–4643 We report three neonates with transient hypoparathyroidism with elevated parathyroid hormone (PTH) levels to clarify further the pathogenesis of late neonatal hypocalcemia and calcium homeostasis. Clinical signs were seizures starting at the age of 10 and 11 days. The biochemical features were characterized by transient hypocalcemia and hyperphosphatemia due to a high transport maximum of the phosphate/glomerular filtration rate, despite high PTH levels. All had normal magnesium and calcidiol levels (at least 5 μg/l) for their age, and this precludes hypoparathyroidism due to low magnesium levels and hyperparathyroidism due to overt vitamin D deficiency. To diagnose pseudohypoparathyroidism type I, intravenous human PTH (1–34) infusions were performed; however, they showed brisk responses of plasma and/or urine cyclic AMP in response to the PTH infusion, but the phosphaturic response to the PTH was sluggish compared to the controls. All three showed an increase in serum alkaline phosphatase activity, suggesting PTH stimulation of osteoblasts. They were treated initially with calcium lactate or (1α)-hydroxycalciol/calcitriol. Their hypoparathyroid condition, however, was transient: they maintained normal serum calcium and PTH levels without medication before the age of 6 months. The etiology, possibly intracellular signal transduction distal to cyclic AMP and/or distinct from adenylate cyclase in the kidney, is developmental and the condition was resolved completely within 6 months of age. We have termed this condition "transient pseudohypoparathyroidism of the neonate". M Minagawa, Department of Pediatrics, Chiba University School of Medicine, 1-8-1 Inohana, Chuo-ku, Chiba 260, Japan
