Phoniatric, Audiological, Orodental and Speech Problems in a Boy with Cardio-Facio-Cutaneous Syndrome Type 3 (CFC 3) Due to a Pathogenic Variant in - Case Study.

Cardio-facio-cutaneous syndrome 3 (CFC3) due to variants in is a rare genetic disorder manifested mainly by short stature, facial dysmorphism, abnormalities of the cardiovascular system, skin changes, and intellectual disability. The aim of the study is the evaluation of the occurrence of pathological changes in the upper respiratory tract, orthodontic disorders, as well as voice, speech and hearing abnormalities in an 11-year-old boy with CFC3 syndrome. The lack of detailed diagnostics of speech, voice and hearing disorders, as well as the degree of their severity was an inspiration to undertake research in this field.

Recurrence risks for different pregnancy outcomes and meiotic segregation analysis of spermatozoa in carriers of t(1;11)(p36.22;q12.2).

Cumulative data obtained from two relatively large pedigrees of a unique reciprocal chromosomal translocation (RCT) t(1;11)(p36.22;q12.2) ascertained by three miscarriages (pedigree 1) and the birth of newborn with hydrocephalus and myelomeningocele (pedigree 2) were used to estimate recurrence risks for different pregnancy outcomes.

[Systemic sclerosis. Part 1: searching for genetic determinants].

Familial aggregation of systemic sclerosis observed in the 1970 of twenty century, the presence of karyotype instability and chromosomal mosaicism and positive associations of certain polymorphisms of genes located in specific regions of the human genome may indicate the important contribution of genetic factors in the development and progression of the disease. The purpose of this paper is to present data on genetic changes found in scleroderma. Despite the enormous progress of research it is not yet clear, which disturbances in a specific way determine onset and development of the disease and which are non-specific forms of molecular abnormalities also present in other diseases with similar clinical symptoms.
