Clinical and laboratory findings in babies with neonatal transient hypothyroidism with or without the 2268insT mutation, and in 20 control subjects
| No | M/F | GA<38 weeks | FH | TSH* ⩾80 μU/ml | T4* <25.8 nmol/l | AB | TSH†(μU/ml) | T4† (nmol/l) | |
|---|---|---|---|---|---|---|---|---|---|
| Values of TSH and T4 are mean (SD); all other values are numbers of affected/non-affected. p Values are for comparisons between 2268insT(+) and 2268insT(−). Comparisons of differences among three groups, p<0.0001 for TSH; p = 0.409 for T4. | |||||||||
| *Measured at initial confirmatory diagnosis; †measured after T4 withdrawal. | |||||||||
| M/F, Males/females; GA, gestational age; FH, positive family history; TSH, thyroid stimulating hormone; AB, antibody; T4, thyroxine. | |||||||||
