A C1-inhibitor rare mutation: Early diagnosis of hereditary angioedema in a paediatric patient

Hereditary angioedema secondary to C1-inhibitor deficiency is a rare autosomal dominant disorder characterized by a deficiency of C1 esterase inhibitor.An eight-year-old girl showed periorbital painless swelling, diagnosed as ethmoiditis. A craniofacial scan did not evidence a paranasal sinus involvement, C1INH levels were undetectable, with low C4 levels: 7.6 mg/dl and C1INH: <8.46 mg/dl. The genetic study identified a rare mutation of the C1INH gene. This clinical report is of relieve because paediatric cases described in literature are rare, did not presented a positive family history, and received a diagnosis after many attacks. Furthermore our girl received a prompt diagnosis of HAE at…

Identification of a new nonsense mutation (Tyr129Stop) of the SRY gene in a newborn infant with XY sex-reversal.

Point mutations and deletions of SRY gene have been described in several cases of XY gonadal dysgenesis. To date, most of these mutations affect the HMG domain of SRY which plays a central role in DNA binding activity of SRY. We report on a non-mosaic XY sex-reversed newborn girl (completely female external genitalia). The direct sequencing of SRY showed a new nonsense mutation in a codon of SRY gene flanking the 3' end of the HMG domain: a thymine is replaced by a guanine at position +387 in codon 129, resulting in the replacement of the amino acid tyrosine (TAT) by a stop codon (TAG). The new mutation of this patient provides further evidence to support the functional importance of the pu…
