T1 |
0-147 |
Sentence |
denotes |
A novel mutation in the connexin 26 gene (GJB2) in a child with clinical and histological features of keratitis-ichthyosis-deafness (KID) syndrome. |
T2 |
148-159 |
Sentence |
denotes |
BACKGROUND: |
T3 |
160-343 |
Sentence |
denotes |
Keratitis-ichthyosis-deafness (KID) syndrome is a rare congenital ectodermal disorder, caused by heterozygous missense mutation in GJB2, encoding the gap junction protein connexin 26. |
T4 |
344-454 |
Sentence |
denotes |
The commonest mutation is the p.Asp50Asn mutation, and only a few other mutations have been described to date. |
T5 |
455-459 |
Sentence |
denotes |
AIM: |
T6 |
460-624 |
Sentence |
denotes |
To report the fatal clinical course and characterize the genetic background of a premature male neonate with the clinical and histological features of KID syndrome. |
T7 |
625-633 |
Sentence |
denotes |
METHODS: |
T8 |
634-730 |
Sentence |
denotes |
Genomic DNA was extracted from peripheral blood and used for PCR amplification of the GJB2 gene. |
T9 |
731-780 |
Sentence |
denotes |
Direct sequencing was used for mutation analysis. |
T10 |
781-789 |
Sentence |
denotes |
RESULTS: |
T11 |
790-1014 |
Sentence |
denotes |
The clinical features included hearing impairment, ichthyosiform erythroderma with hyperkeratotic plaques, palmoplantar keratoderma, alopecia of the scalp and eyelashes, and a thick vernix caseosa-like covering of the scalp. |
T12 |
1015-1181 |
Sentence |
denotes |
On histological analysis, features characteristic of KID syndrome, such as acanthosis and papillomatosis of the epidermis with basket-weave hyperkeratosis, were seen. |
T13 |
1182-1251 |
Sentence |
denotes |
The skin symptoms were treated successfully with acitretin 0.5 mg/kg. |
T14 |
1252-1343 |
Sentence |
denotes |
The boy developed intraventricular and intracerebral haemorrhage, leading to hydrocephalus. |
T15 |
1344-1502 |
Sentence |
denotes |
His condition was further complicated by septicaemia and meningitis caused by infection with extended-spectrum beta-lactamase-producing Klebsiella pneumoniae. |
T16 |
1503-1613 |
Sentence |
denotes |
Severe respiratory failure followed, and the child died at 46 weeks of gestational age (13 weeks postnatally). |
T17 |
1614-1809 |
Sentence |
denotes |
Sequencing of the GJB2 gene showed that the child was heterozygous for a novel nucleotide change, c.263C>T, in exon 2, leading to a substitution of alanine for valine at position 88 (p.Ala88Val). |
T18 |
1810-1822 |
Sentence |
denotes |
CONCLUSIONS: |
T19 |
1823-1949 |
Sentence |
denotes |
This study has identified a new heterozygous de novo mutation in the Cx26 gene (c.263C>T; p.Ala88Val) leading to KID syndrome. |
