48,XYYY syndrome: a rare Y trisomic (chromosome number) intersex variation characterized by mild-moderate developmental delay (especially speech), regular to mild intellectual disability, large, irregular teeth with delicate enamel, tall stature, and acne. Radioulnar stenosis and clinodactyly have also been associated. Children generally present typical genitalia, while hypogonadism and infertility is frequently reported in adults. It's often described as CTM karyotype with two extra Y.

Pentasomy X, also known as 49,XXXXX and quintuple-X, is a chromosomal condition in which an individual has five X chromosomes instead of two.

49,XYYYY Karyotype: a rare Y chromosome number condition with a variable phenotype mainly characterized by moderate to severe intellectual disability, speech delay, hypotonia, and mild dimorphic features, including facial asymmetry, hypertelorism, bilateral low set 'lop' ears, and micrognatia. 

Tetrasomy X (also called quadruple-X or 48,XXXX) is an extremely rare chromosomal condition caused by the presence of four X chromosomes.
