Identification of a Novel IGSF1 Variant in Two Malaysian Male Siblings with Central Hypothyroidism and Macroorchidism
J Clin Res Pediatr Endocrinol. 2024 Apr 22. doi: 10.4274/jcrpe.galenos.2024.2023-12-1. Online ahead of print.ABSTRACTIGSF1 mutation is the commonest cause of mild to moderate isolated central congenital hypothyroidism and has an X-linked recessive inheritance, primarily affecting males. Other notable clinical features are macroorchidism with delayed pubertal testosterone rise, large birth weight, increased body mass index, low prolactin, transient growth hormone deficiency and low prolactin. Two male siblings with central hypothyroidism were found to have a novel IGSF1 c.3467T>A variant that was likely pathogenic based ...

Exploring Multiple Endocrinological Issues and Dysautonomia in a Rare Case: Hypoparathyroidism in MIRAGE Syndrome
We present a 6.5-year-old girl, who was first admitted to our department with short stature. On follow up, she exhibited multiple endocrinological issues, including transient hypothyroidism, primary hypoparathyroidism and dysautonomia, along with multisystem involvement. Further investigations revealed recurrent moniliasis, low IgM levels, and transient monosomy 7 in the bone marrow. Whole exome sequencing revealed a heterozygous pathogenic variant of SAMD9 (c.2159del; p.Asn720ThrfsTer35). Additional complications observed during follow-up included medullary nephrocalcinosis, hypomagnesemia, hypermagnesiuria, hypophosphate...
