Frequency and type of incontinence and its association with other variables were assessed in females with Rett Syndrome (RS)
(n = 63), using an adapted Dutch version of the ‘Parental Questionnaire: Enuresis/Urinary Incontinence’ (Beetz et al. 1994). Also, incontinence in RS was compared to a control group consisting of females with non-specific (mixed) intellectual disability
(n = 26). Urinary incontinence (UI) (i.e., daytime incontinence and nocturnal enuresis) and faecal incontinence (FI) were found
to be common problems among females with RS that occur in a high frequency of days/nights. UI and FI were mostly primary in
nature and occur independent of participants’ age and level of adaptive functioning. Solid stool, lower urinary tract symptoms
and urinary tract infections (UTI’s) were also common problems in females with RS. No differences in incontinence between
RS and the control group were found, except for solid stool that was more common in RS than in the control group. It is concluded
that incontinence is not part of the behavioural phenotype of RS, but that there is an increased risk for solid stool in females
with RS. 相似文献

Long non-coding RNAs have been implicated in the regulation of a plethora of biological processes, yet it has been challenging to verify that they are truly not coding for proteins. Terminal differentiation-induced non-coding RNA (TINCR) is a 3.7-kilobase mRNA that is highly abundant in epidermal keratinocytes prior to cornification. Here, we report the presence of an evolutionarily conserved open reading frame in TINCR and the identification of peptides derived from this open reading frame in the proteome of human stratum corneum. Our results demonstrate that TINCR is a protein-coding RNA and suggest that the TINCR-encoded protein is involved in keratinocyte cornification. 相似文献
