Familial primary open-angle glaucoma: a case report

K. Shi, Zhao, L., and Wang, C. Y., Familial primary open-angle glaucoma: a case report, vol. 13. pp. 3162-3164, 2014.

Primary open-angle glaucoma (POAG) is a disease that is often inherited, but the rules governing its inheritance are inconclusive. Herein, we report a case of POAG in a Chinese family. A 25-year-old female patient was referred to our department with progressive visual acuity decline in her left eye for the past 3 years. Ophthalmological examination supported our diagnosis of POAG in both eyes. We recorded the case history and clinical data of the proband and her family members and followed standard genetic study procedures.

Comparative multiplex dosage analysis in spinocerebellar ataxia type 2 patients

F. Calì, Chiavetta, V., Ragalmuto, A., Vinci, M., Ruggeri, G., Schinocca, P., and Romano, V., Comparative multiplex dosage analysis in spinocerebellar ataxia type 2 patients, vol. 12, pp. 1176-1181, 2013.

We developed a new application of comparative multiplex dosage analysis (CMDA) for evaluation of the ataxin 2 gene. Expansions of the triplet CAG can cause spinocerebellar ataxia type 2 (SCA2), a neurodegenerative disease with an autosomal-dominant mode of inheritance. Molecular diagnosis of SCA2 is routinely based on the use of conventional PCR to detect the CAG expansion. However, PCR does not amplify an allele with an expansion of many triplets (>80), which is typically found in infantile and juvenile forms of SCA2, thus leading to false negatives.

Sulcus vocalis: evidence for autosomal dominant inheritance

R. H. G. Martins, Gonçalves, T. M., Neves, D. S., Fracalossi, T. A., Tavares, E. L. M., and Moretti-Ferreira, D., Sulcus vocalis: evidence for autosomal dominant inheritance, vol. 10, pp. 3163-3168, 2011.

We found evidence of autosomal dominant hereditary transmission of sulcus vocalis. Four dysphonic patients from three generations of the same family were submitted to videolaryngoscopic examination (three patients) and to direct laryngoscopy (one patient) to diagnose the hoarseness. Sulcus vocalis was diagnosed in all four patients.
