En 2 de 12 pacientes (16,6%) se detectaron estas mutaciones: uno heterocigoto compuesto de genotipo c.1103C>T/c.2242G>A y el otro heterocigoto c.2242G>A, el segundo probablemente presente una expresión monoalélica del gen mutado. [repositorio.uchile.cl]

Workup
Radiological Workup The imaging modalities such as ultrasound and scintigraphy can help in defining the etiology of CH and also predict whether it is transient or permanent type of CH. [jcnonweb.com]
Treatment
The initiation of treatment within first 2 weeks of life is crucial for the normal neurodevelopment. [31] Dosing Levothyroxine (L-T4) is the only recommended treatment for replacement therapy. [jcnonweb.com]
A T 4 less than 6.5 mcg/dL and a TSH greater than 20 mIU/L indicate abnormal values necessitating treatment with levothyroxine at a dose of 10 to 15 mcg/kg/day. 20 Treatment should be initiated as early as possible, since delayed treatment increases the [uspharmacist.com]
Management and treatment Levothyroxine is the treatment of choice (starting dose 10-15mcg/kg/day), with the immediate goal to raise the serum T4 above 130 nmol/L (10 ug/dL) as rapidly as possible; with these doses, serum TSH usually normalizes in 2-4 [orpha.net]

The etiology of CH was different from that reported in many other studies. The most common etiology of CH was dyshormonogenesis. [16] Female-to-male ratio was not similar to other studies in this field, which showed female predominance. [advbiores.net]
The etiology of TD, which is the most common cause of CH, is largely unknown. [dovepress.com]
Etiology Dyshormonogenesis is caused by hereditary defects in the steps of thyroid hormone synthesis and secretion, the majority of which are transmitted in an autosomal recessive manner but at least one condition has autosomal dominant inheritance. [orpha.net]
