What are the possible diagnoses for a 20-week fetus with oligohydramnios, a large nuchal fold, and no visible stomach bubble, given low-risk trisomy screening and a 25-year-old mother?

The clinical evaluation must consider the possibility of trisomy 18, Down syndrome, and other genetic or structural syndromes in the presence of oligohydramnios, an enlarged nuchal fold, and absent stomach bubble at the 20-week gestational scan, despite low-risk trisomy screening results.
