  • Should we screen carriers of maternally inherited SDHD mutations?
    Jean-Pierre Bayley

    Dear Editor,

    We are writing to comment on a recent paper published in your journal by Burnichon and colleagues: Burnichon N, et al. Risk assessment of maternally inherited SDHD paraganglioma and phaeochromocytoma. J Med Genet. 2017; 54:125-133.

    In this paper a case study is presented describing development of pheochromocytoma in a carrier of an SDHD mutation. Although at first sight not an uncommon occu...

  • NONO mutations and non compaction cardiomyopathy
    Eyal Reinstein

    The association has been described before but is not cited in the JMG manuscript

    Eur J Hum Genet. 2016 Jun 22. doi: 10.1038/ejhg.2016.72.

    Intellectual disability and non-compaction cardiomyopathy with a de novo NONO mutation identified by exome sequencing.

  • Re:NONO mutations and non compaction cardiomyopathy
    Daryl Armstrong Scott

    We only became aware of the paper by Reinstein et al. after our manuscript was published online. It is gratifying to know that we are not the only group who has identified left ventricular non-compaction (LVNC) in males with loss-of-function mutations in NONO.

    Conflict of Interest:

  • Re:A p.R464 H variation in the CCDC88C gene may not cause a dominant form of spinocerebellar ataxia
    Edwin Ho-Yin Chan

    To the Editor of Journal of Medical Genetics:

    Enabled by recent advances in sequencing technologies, genotypes from thousands of individuals are now available in online databases. While most of them aim to be the reference source of genotypes from healthy individuals, however, due to the lack of accompanying clinical data, geneticists now face the challenge of separating pathogenic mutations and rare polymorphisms. The fr...

  • A p.R464 H variation in the CCDC88C gene may not cause a dominant form of spinocerebellar ataxia
    Yoshihisa Takiyama

    To the editor:

    The report that a novel missense mutation in CCDC88C activates the JNK pathway and causes a dominant form of spinocerebellar ataxia that appeared in your Journal (1) is of great interest. Although we identified the same heterozygous missense variation (c.1391G>A, p.R464H) as that reported (1) in a Japanese patient with autosomal dominant cerebellar ataxia (ADCA), we report here that this varia...

  • Re:The putative role of Podxl in autosomal-recessive juvenile Parkinsonism
    B K. Thelma

    Response to e letter ID jmedgenet el; 2826 by Refaeli et al., dated June14, 2016 A considerable amount of literature on the role of podocalyxin-like (PODXL) protein in normal mammalian kidney functions and to a lesser extent in mouse brain development is available. We agree that these studies particularly, "Anuria, Omphalocele, and Perinatal Lethality in Mice Lacking the Cd34-Related Protein Podocalyxin" by Doyonnas et...

    In the February 2016 edition of the Journal of Medical Genetics, Sudhaman et al(1) report the identification of a PODXL variant (c.89_90insGTCGCCCC) as the causative mutation in an Indian fam...

  • Against all odds
    June Strada

    I just read the articles on SMA1, SMA2, SMA3. I felt it important to tell you of my son, born 1/26/70. When I took him to his first checkup at 3 months old, I voiced my concern for his floppy head. Again at 6 months old, when he couldn't sit up, roll over, kick against resistance. Finally, the Pediatrician agreed to get an appointment with Yale Hospital in CT at 8 mos. The biopsy was shown to be SMA 1. We weren't given...

  • A case for agreed nomenclature?
    Elizabeth Mary Tuckerman

    Dear Editor

    I would like to draw to the attention of your readers that the pair of twins described in this report[1] are the same twins that we described in our paper Tuckerman et al.[2] I feel that failing to directly quote our paper was rather an oversight by Willemsen et al. on a number of counts.

    First, our paper contains a more detailed family history and description of the twins...
