A new FOXE1 homozygous frameshift variant expands the genotypic and phenotypic spectrum of Bamforth-Lazarus syndrome.

Bamforth-Lazarus syndrome is a rare autosomal recessive disease caused by biallelic loss-of-function variants in the FOXE1 gene. The condition is characterized by congenital hypothyroidism due to thyroid agenesis or thyroid hypoplasia, cleft palate, spiky hair, with or without choanal atresia, and bifid epiglottis. To date, seven pathogenic variants have been reported in the FOXE1 gene causing Bamforth-Lazarus syndrome.

Prevalence and functional significance of 25-hydroxyvitamin D deficiency and vitamin D receptor gene polymorphisms in Asian Indians.

Background: Recent studies show a wide prevalence of hypovitaminosis D in Asian Indians.

Objective: The objective was to assess the functional significance of 25-hydroxyvitamin D [25(OH)D] deficiency, vitamin D receptor (VDR) gene, and parathyroid hormone (PTH) gene polymorphisms in relation to bone mineral density (BMD) in urban Asian Indians.

Design: Serum total calcium, inorganic phosphorus, alkaline phosphatase, 25(OH)D, intact PTH, and BMD at lumbar spine, proximal femur, and forearm were measured in 105 adult subjects.
