In some cases, karyotype evolution can be observed if repeated cytogenetic analyses are performed, unraveling the stepwise accumulation of secondary abnormalities with the starting point of a primary abnormality.
A variety of primary or secondary abnormalities in dystrophin-associated proteins are involved in several forms of limb-girdle muscular dystrophy, congenital muscular dystrophy, and dystroglycanopathy [ 7– 9].
It appears that ERT resolved lysosomal pathology in the majority of fibers, whereas autophagic accumulation and inclusions - the major secondary abnormalities - persisted.
Rectocele and enterocele are defects of the posterior vaginal compartment, although they can be secondary to abnormalities of the central compartment, since lesions of the perineal raphe and rectovaginal septum can occur in isolation or accompanied by others that also affect the tissues involved in pelvic support.
Other secondary cytogenetic abnormalities of clinical interest include MYC translocations and del(1p), both of which has been associated with adverse prognosis in MM.
Although we have not examined any relationship effects in this current study, Berbaum's research suggests that detection of a secondary abnormality is inversely proportional to the severity of the first lesion detected (Berbaum et al. 2001).
The remainder of the underlying laminar pattern was preserved and there was marked astrocytic gliosis, suggesting that these abnormalities may be a secondary abnormality.
Congenital causes are secondary to genetic abnormalities of myocardial ion channels [3].
It is also possible that the presence of pathogens in asthmatic airways is secondary to mucosal abnormalities of as yet unknown cause.
In all patients with primary hypothyroidism, a thyroid-stimulating hormone (TSH) level of greater than 20 mU/L was taken along with low total and/or free T4, and in patients with secondary hypothyroidism, structural abnormalities of hypothalamo-pituitary area along with low total and/or free T4 were considered diagnostic.
