The phrase "abnormalities in the formation" is correct and usable in written English.
It can be used in contexts related to medical, biological, or structural discussions where deviations from the norm in development or construction are being described.
Example: "The study revealed several abnormalities in the formation of the heart during early development."
Alternatives: "irregularities in the development" or "anomalies in the structure".
These include a greater susceptibility to atherosclerosis [Circulation 15 (1998 2738]], immunodeficiencies linked to the overexpression of inflammatory cytokines [J. Neurochem. 58 (1992) 192], abnormalities in the formation and maintenance of bone tissue [Proc. Natl. Acad. Sci. USA 97 (2000 9197]] and changes in muscle differentiation [Nucleic Acids Res. 27 (1999) 411].
These early postnatal changes in maturation are not accompanied by abnormalities in the formation of a functional skin barrier.
The stage-specific RNAi before 3L significantly increased the frequency of lethality, and about 75% of the adult flies had abnormalities in the formation of their wings and abdominal stripes (Figure 4B).
Both the studies showed, for animals with decreased activity of CK, abnormalities in the formation and maintenance of hippocampal mossy fiber connections.
Anything more than minor abnormalities in the formation of the ventricular myocardium during embryonic life are likely to result in death of the embryo.
In the late 1990s, Wallukat et al proposed that pre-eclampsia is a pregnancy-induced autoimmune disease in which the abnormalities in the formation of the placenta result from circulating autoantibodies that react with, and activate the AT1 receptor (Wallukat et al, 1999).
The cause of cutis laxa is unknown, but the defect appears to be an abnormality in the formation or structure of the protein elastin, the principal component of the elastic connective tissues of the skin; as a result, degenerative changes occur in the elastic fibres.
Although an obvious abnormality in the formation of IEMs was observed in CKO skin, the expression and localization of skin differentiation markers and junctional proteins were comparable to those in control skin (Fig. 4C, F L).
Using magnetic resonance imaging (MRI) we detected functional abnormalities in the hippocampal formation of patients with septic delirium.
PEX13 brain mutants exhibit numerous morphological abnormalities, notably defects in the formation of several folia and their separating fissures, particularly fissures (i.e. declival, intercrural and uvular fissures) that form after P5.
Males also displayed abnormalities in formation of the sensory rays, where the rays did not fully extend and the cuticular fan was reduced in size compared with controls (Figure 2e f).
