Autosomal dominant inheritance of conductive deafness due to stapedial anomalies, external ear malformations and congenital facial palsy

AbstractA number of minor variations to the configuration of the external ear are well recognized. This paper brings attention to one entity which is characterized by a small cartilaginous nodule or prominence arising from the posterior surface of the pinna and which we have named Quelprud's nodule. A prospective clinical survey of 208 patients attending an ENT clinic revealed that nearly one-third of the population studied possess this nodule. There was an equal sex incidence. The Quelprud's nodule was identified within families in a distribution which suggests an autosomal dominant inheritance with variable expressivity.

AbstractIn studies of families with rare disease, it is common to screen for de novo mutations, as well as recessive or dominant variants that explain the phenotype. However, the filtering strategies and software used to prioritize high-confidence variants vary from study to study. In an effort to establish recommendations for rare disease research, we explore effective guidelines for variant (SNP and INDEL) filtering and report the expected number of candidates for de novo dominant, recessive, and autosomal dominant modes of inheritance. We derived these guidelines using two large family-based cohorts that underwent whole-genome sequencing, as well as two family cohorts with whole-exome sequencing. The filters are applied to common attributes, including genotype-quality, sequencing depth, allele balance, and population allele frequency. The resulting guidelines yield ~10 candidate SNP and INDEL variants per exome, and 18 per genome for recessive and de novo dominant modes of inheritance, with substantially more candidates for autosomal dominant inheritance. For family-based, whole-genome sequencing studies, this number includes an average of three de novo, ten compound heterozygous, one autosomal recessive, four X-linked variants, and roughly 100 candidate variants following autosomal dominant inheritance. The slivar software we developed to establish and rapidly apply these filters to VCF files is available at https://github.com/brentp/slivar under an MIT license, and includes documentation and recommendations for best practices for rare disease analysis.

Lung Cancer Patients

e20511 Background: Smoking and air pollution are the major causes of lung cancer; however, numerous studies have demonstrated that genetic factors also contribute to the development of lung cancer. Here, we reported an analysis of genomic features in 65 lung cancer patients with autosomal-dominant or autosomal-recessive inheritance of germline mutations. Methods: We retrospectively reviewed next-generation sequencing data of 26,904 lung cancer patients in a Chinese cohort. The germline mutation patterns, as well as the co-occurrence with somatic driver mutations were analyzed. Results: A total of 65 (0.24%) patients with heterozygous germline mutations associated with hereditary cancer syndromes were detected, including 27 (0.10%) patients with autosomal-dominant inheritance (BRCA1, BRCA2, RET and TP53) and 38 (0.14%) patients with autosomal-recessive inheritance (ATM, BLM, FANCA, FANCG, MUTYH, NBN, RECQL4 and WRN). Comparing to patients with autosomal-dominant inheritance (Age 56±17.8), patients with autosomal-recessive inheritance (Age 65±11.7, P = 0.009) were older, and there is no gender difference. Additionally, 66.7% (18/27) of patients with autosomal-dominant inheritance were identified co-mutated actionable variations, such as 12 patients harboring mutations in exon 18–21 of EGFR, 2 patients harboring ERBB2 exon 20 insertions, 3 patients harboring mutations in exon 2 of KRAS and 1 patient harboring EML4-ALK fusion. The coexistence of germline autosomal-dominant mutations and somatic driver mutations indicated that germline mutations have weak impact on lung cancer. Simultaneously, 52.6% (20/38) of patients with autosomal-recessive inheritance were identified co-mutated actionable variations, such as 15 EGFR+ patients, 2 ERBB2+ patients and 3 KRAS+ patients. And there was no significant difference in population frequency of co-mutated actionable variations between the two groups. Conclusions: In summary, studies on germline mutations of lung cancer patients may help to elucidate the etiology and mechanism of lung cancer, and may help for early detection and diagnosis, targeted therapy and improved prevention strategies.

Male To Female

A family is described in which four persons in three generations suffered spontaneous pneumothoraces: a newborn, an infant, an adolescent, and an adult. Review of the literature reveals 61 reports of familial spontaneous pneumothorax in 22 families. The ratio of male to female cases is approximately 1.8. Affected parents and affected children (including affected fathers and sons) are seen in ten families, while affected siblings with unaffected parents are noted in 13 families. Consanguinity has not been reported. Although autosomal dominant inheritance has been suggested as an explanation of familial spontaneous pneumothorax, available pedigree data are not adequate for statistical analysis. Physicians should be aware of the familial occurrence of spontaneous pneumothorax so that members of such families may be appropriately managed when problems arise.
