Specialty. Medical genetics. Distal 18q- is a genetic condition caused by a deletion of genetic material within one of the two copies of chromosome 18. [1] The deletion involves the distal section of 18q and typically extends to the tip of the long arm of chromosome 18. [2]
Individuals with ring 18 have one of their two copies of chromosome 18 that has formed the shape of a ring. The ring is formed when the caps on both the long arm (q) and the short arm (p) of one copy of chromosome 18 are lost and the new ends re-join to form the ring. Because the ring involves deletions of both the long arm (18q-) and the short ...
Proximal 18q-is a rare genetic condition caused by a deletion of genetic material within one of the two copies of chromosome 18. This deletion involves the proximal (near the centromere ) section of the long arm of chromosome 18 somewhere between 18q11.2 (18.9 Mb) to 18q21.1 (43.8 Mb). [1]

Y chromosome microdeletion. Y chromosome microdeletion (YCM) is a family of genetic disorders caused by missing genes in the Y chromosome. Many men with YCM exhibit no symptoms and lead normal lives. It is present in a significant number of men with reduced fertility. [1] Reduced sperm production varies from oligozoospermia, significant lack of ...
