A new HLA‐DQB1 allele, HLA‐DQB1 *04:62 , identified in a Chinese family

Puberty is a challenging time for both children and parents. Many researches about parenting in puberty time have been done in the western culture context. Due to Chinese parents' special philosophy of parenting, it is valuable and interesting to probe the this parenting-related issue in Chinese context. Unfortunately, there was few study to do so. As the supplement for previous research, this study aimed to discuss Chinese parenting behaviors during children's early adolescent time by introducing two interviews with a parent of early adolescent boy and a parent of a girl in early adolescence respectively. It's found that the Chinese parenting style can be explained from 3 aspects: aims of parenting, basic idea of parenting, expectations to kid. No matter for boy or girl, the parenting involves supervision and understanding and love, which is a kind of unique style shared in Chinese family education culture. Besides, parent gives more expectation about parent-child communication to girl.

Sensory Defect

Nonsyndromic hereditary hearing loss is a common sensory defect in humans that is clinically and genetically highly heterogeneous. So far, 122 genes have been associated with this disorder and 50 of them have been linked to autosomal dominant (DFNA) forms like DFNA68, a rare subtype of hearing impairment caused by disruption of a stereociliary scaffolding protein (HOMER2) that is essential for normal hearing in humans and mice. In this study, we report a novel HOMER2 variant (c.832_836delCCTCA) identified in a Spanish family by using a custom NGS targeted gene panel (OTO-NGS-v2). This frameshift mutation produces a premature stop codon that may lead in the absence of NMD to a shorter variant (p.Pro278Alafs*10) that truncates HOMER2 at the CDC42 binding domain (CBD) of the coiled-coil structure, a region that is essential for protein multimerization and HOMER2-CDC42 interaction. c.832_836delCCTCA mutation is placed close to the previously identified c.840_840dup mutation found in a Chinese family that truncates the protein (p.Met281Hisfs*9) at the CBD. Functional assessment of the Chinese mutant revealed decreased protein stability, reduced ability to multimerize, and altered distribution pattern in transfected cells when compared with wild-type HOMER2. Interestingly, the Spanish and Chinese frameshift mutations might exert a similar effect at the protein level, leading to truncated mutants with the same Ct aberrant protein tail, thus suggesting that they can share a common mechanism of pathogenesis. Indeed, age-matched patients in both families display quite similar hearing loss phenotypes consisting of early-onset, moderate-to-profound progressive hearing loss. In summary, we have identified the third variant in HOMER2, which is the first one identified in the Spanish population, thus contributing to expanding the mutational spectrum of this gene in other populations, and also to clarifying the genotype–phenotype correlations of DFNA68 hearing loss.
