A homozygous female hemophilia A

BACKGROUND:

Hemophilia A (HA), being an X-linked recessive disorder, females are rarely affected, although they can be carriers.

AIMS:

To study the mutation in F8 gene in an extended family with a homozygous female HA.

MATERIALS AND METHODS:

All the seven affected members (six males and one female) were initially screened by Conformation Sensitive Gel Electrophoresis (CSGE) and direct DNA sequencing.

RESULTS:

A homozygous missense mutation c.1315G>A (p.Gly420Ser) was identified in exon 9 of F8 gene in homozygous state in the affected female born of 1° consanguinous marriage and in all the affected male members of the family. Her factor VIII levels was found to be 5.5%, vWF:Ag 120%.

CONCLUSION:

In India, as consanguineous marriages are very common in certain communities (up to 30%), the likelihood of encountering female hemophilia is higher, although this is the first case of HA out of 1600 hemophilia families registered in our Comprehensive Haemophilia Care Center. Genetic diagnosis in such cases is not necessary as all the male children will be affected and daughters obligatory carriers.     

Aminopeptidase A is angiotensinase A

Summary Quantitative histochemical measurements of aminopeptidase A (APA; E.C.3.4.11.7) were done kinetically in the kidney glomeruli of rat and mouse with an instrumental setup consisting of a microdensitometer and a computer-supported morphometric system. The histochemical demonstration of APA was carried out using the simultaneous azo coupling technique (purest-grade Fast Blue B as coupling agent and -l-glutamic acid-4-methoxy-2-naphthylamide as substrate). The methodological studies show that APA activity is calcium-ion-dependent and increases linearly with the thickness of the tissue section (3–12 m) and that the time-course of APA activity as determined by linear regression is linear only for the first 1 to 2 min of the reaction. — Kinetic measurements indicate a 40% decrease in APA activities when -l-glutamic acid-4-methoxy-2-naphthylamide (-l-Glu-MNA) is replaced by -l-aspartic acid-4-methoxy-2-naphthylamide. When -l-Glu-MNA is replaced with l-alanine-4-methoxy-2-naphthylamide, which is a substrate of aminopeptidase M (APM) only very low reaction rates are measurable (about 1.4% of those with -l-Glu-MNA). 100 and 130 mM NaCl in the incubation medium increase APA activities by approximately 16%–17%. — To clarify the functional importance of APA in the kidney, their activities were measured under the influence of angiotensins. The glomerulus was selected as the measuring site, for besides APA it contains no APM or other peptidases that could degrade angiotensins (the glomerular dipeptidyl peptidase IV is not inhibited by angiotensin II). Using the Lineweaver-Burk plot, we determined a K _m of 0.16 mM for the APA in rat glomeruli and 0.14 mM in mouse glomeruli. The V _max in mouse glomeruli is 1.6 times higher than in rat glomeruli. Ang iotensin I, II and III competitively inhibit APA in the rat and mouse glomeruli. — With quantitative histochemical techniques it was possible to show that APA is equivalent to angiotensinase A (splitting off the N-terminal aspartic acid from angiotensin I and II).Supported by the Deutsche Forschungsgemeinschaft (SFB 105)

Quadruplexes of human telomere DNA analogs designed to contain G:A:G:A,G:G:A:A,and A:A:A:A tetrads

Replacement of two to four guanines by adenines in the human telomere DNA repeat dG₃(TTAG₃)₃ did not hinder the formation of quadruplexes if the substitutions took place in the terminal tetrad bridged by the diagonal loop of the intramolecular antiparallel three‐tetrad scaffold, as proved by CD and PAGE in both Na⁺ and K⁺ solutions. Thermodynamic data showed that, in Na⁺ solution, the dG₃(TTAG₃)₃ quadruplex was destabilized, the least by the two G:A:G:A tetrads, the most by the G:G:A:A tetrad in which the adenosines replaced syn‐guanosines. In physiological K⁺ solution, the highest destabilization was caused by the 4A tetrad. In K⁺, only the unmodified dG₃(TTAG₃)₃ quadruplex rearranged into a K⁺‐dependent quadruplex form, none of the multiple adenine‐modified structures did so. This may imply biological consequences for nonrepaired A‐for‐G mutations. © 2010 Wiley Periodicals, Inc. Biopolymers 93: 880–886, 2010.
