In thalassaemic patients, the impact of the disease especially on quality of life (QOL) of the caregivers in Malaysia has not been established. This study was conducted to assess the health-related quality of life (HRQOL) of thalassaemia patients and their caregivers in order to explore factors affecting their QOL. A cross-sectional study was conducted on 75 thalassaemic children and adolescents aged between 7 and 18 years old and their caregivers. The PedsQLTM 4.0
generic core scales questionnaire was administered to both thalassaemic children and their caregivers while the health questionnaire EQ 5D was given to caregivers only. The subjects were recruited from Hospital Kuala Lumpur (HKL) and Universiti Kebangsaan Malaysia Medical Centre (UKMMC). The results revealed that the mean of psychosocial HRQOL score in patients (63.91±14.65) was significantly lower than parent proxy reports (67.14±10.48) (p=0.008). The
school functioning score (50.59±15.31) was the lowest of the psychosocial measure, followed by emotional functioning (59.92±16.83) and social functioning (78.01±13.92) score. The patients’ pre-transfusion haemoglobin concentration was significantly associated with their QOL (p=0.02). Having more children, higher numbers of thalassaemic children and lower educational level of caregivers were associated with poorer QOL. In conclusion, caregivers underestimated
the QOL of their thalassaemic children. The school functioning domain was affected the most domain. There is a need to improve the QOL of thalassaemic children and their caregivers.
VACTERL association is a rare genetic disorder involving at least three of the following congenital
malformations: vertebral defects (V), anal atresia (A), cardiac defects (C), trachea-oesophageal fistula with
or without oesophageal atresia (TE), renal anomalies (R) and limb abnormalities (L). Until now, the
aetiology of VACTERL association is unknown, particularly at the molecular level. Here, we performed
whole exome sequencing (WES) of an infant with VACTERL association. The patient was delivered
prematurely at 30 weeks and had 4/6 of the VACTERL malformations. Trio-WES analysis was performed
using Torrent Suite and ANNOVAR. Polymorphisms with an allele frequency of >0.01 were excluded, and
the remaining variants were filtered based on de novo mutations, autosomal recessive, X-linked and di-genic
inheritance traits. In this patient, no homozygous, compound heterozygous or X-linked mutations was
associated with VACTERL. However, we identified two heterozygous mutations; KIF27
(ENST00000297814: c.3004A> C:p.N1002H) and GNAS (ENST00000371098: c.205C>A:p.H69N) genes that
were inherited from her father and mother respectively. A de novo, IFT140 gene mutation
(ENST00000426508: c.683C>G:p.S228C) was also identified in this patient. The VACTERL phenotype in
this patient may due to heterozygous mutations affecting KIF27 and GNAS genes, inherited via autosomal
recessive trait. In addition, the IFT140 gene mutation may also be involved. These genes are known to be
directly or non-directly involved in the sonic hedgehog signalling that is known to be implicated in
VACTERL. This is the first report of these genetic mutations in association with VACTERL.
The incidence of breast cancer has been on the rise in Malaysia. It is suggested that a subset of breast cancer cases were associated with germline mutation in breast cancer susceptibility (BRCA) genes. Most of the BRCA mutations reported in Malaysia were point mutations, small deletions and insertions. Here we report the first study of BRCA large genomic rearrangements (LGRs) in Malaysia. We aimed to detect the presence of LGRs in the BRCA genes of Malaysian patients with breast cancer.
