What a good idea using practice to support creators in need. Steve's alto playing is as admirable and innovative as always. I love the way in which he includes contemporary music among the sources for jazz as pop culture etc. Looking forward to listening this EP in my car, and to imagine the passenger sitting next to me.

Asn53Ile substitution was present in all affected individuals and absent in all of the unaffected individuals in the pedigree. Genotyping of 1, control individuals Danish medical student volunteers from Aarhus University and anonymous Danish blood donors showed that the mutation was absent among these 2, control chromosomes. To systematically screen for other mutations in CALM1 , we developed a mutation-detection assay for each of the five coding exons on the basis of high-resolution melting HRM of amplified PCR products.
Sixty-three individuals, referred for RYR2 mutation analysis at the Statens Serum Institute in Denmark where genetic testing failed to identify any RYR2 mutation in 61 of these individuals , were analyzed in duplicate. All samples with aberrant melting curves, as well as ten control samples with normal melting curves, were sequenced primer sequences are listed in Table S1.
From this screening a second heterozygous CALM1 missense mutation was identified in an individual of Iraqi origin. The mutation c. DNA sequencing revealed that this mutation was absent in the mother and the father, neither of whom showed signs of heart arrhythmias, demonstrating the presence of a de novo mutation in this individual.
A microsatellite marker analysis confirmed the paternity relationship. The individual with the de novo CALM1 mutation was a year-old female who presented at age 4 with a successfully resuscitated, out-of-hospital cardiac arrest due to VF while she was running.
An initial ECG and echocardiogram were within normal limits, and there was no evidence of QT prolongation not shown. Evaluation of her immediate family was unremarkable. An exercise ECG and electrophysiological study undertaken on full betablockade and right ventricular and coronary angiography were within normal limits. An initial diagnosis of idiopathic VF was made at the time. These appeared to be bidirectional at times.
She fainted twice more in her teens, and at age 15 she suffered a further cardiac arrest. Her mother, aged 62, was asymptomatic until developing heart failure secondary to adriamycin-induced cardiomyopathy from breast cancer treatment.
She did not experience syncope or arrhythmia. An ECG demonstrated left-bundle-branch block and leftward axis deviation. Her father, aged 66, had suffered nonexertional syncope in stressful situations, consistent with vasovagal syncope.
His resting ECG was normal, and exercise testing for atypical chest pain had induced ischemic changes without arrhythmia. An angiogram was reported as showing unobstructed coronaries and vasospasm. Both CALM1 mutations thus appear to induce an early-onset and highly penetrant phenotype that belongs to the severe end of the spectrum of CPVT-like arrhythmias. The fact that p. Asn97Ser is a de novo substitution is fits well with the presentation of the associated disease as a highly malignant form with very early presentation and is consistent with the RYR2 -associated disease, which is commonly caused by de novo mutations.
No missense mutations were identified among these 1, control chromosomes. In contrast, three rare silent polymorphisms were identified these were present among five control individuals Table S4 , stressing the selection pressure against missense mutations in this gene. A specific Iraqi control population was not investigated because the mutation was de novo, and the mutation rate is likely to be the same in all populations. A literature search also failed to present evidence for any previously identified calmodulin mutations.
The presence of three independent genes in the human genome CALM [MIM , and ] , all encoding ubiquitously expressed identical calmodulin protein molecules, further underscores the selection pressure against any amino acid changes in this classic calcium-binding protein.
The p. Because the p. A less likely possibility is that it reflects an increased positive inter-domain cooperativity between the N and C domains. This shift is evidenced by a large increase in fluorescence intensity of the RYR2 Trp residue; calmodulin itself does not contain any Trp residues. Asn97Ser as opposed to p. Asn53Ile and native calmodulin. Asn97Ser, p. Thus, our data demonstrate that for the p. Asn97Ser substitution.
On this basis, we suggest that p. This would also explain how one mutated calmodulin allele out of six encoding identical proteins is sufficient to cause a dominantly inherited phenotype. Asn53Ile substitution did not demonstrate a significantly compromised RYR2 interaction in the experimental setup used here. Thus, it is at present unclear whether the p.

As a consequence of our findings, the three calmodulin genes are candidates for genetic screening of individuals with CPVT-like arrhythmia and unexplained sudden cardiac death.
