When is 1p36 deletion syndrome diagnosed?
Diagnosis. 1p36 deletion syndrome is usually suspected based on the signs and symptoms and confirmed by fluorescence in situ hybridization (FISH). Chromosomal microarray or karyotype analysis may also be used to diagnose 1p36 deletion.
Can a male be born with female chromosomes?
This may be in the same gonad (an ovotestis), or the person might have 1 ovary and 1 testis. The person may have XX chromosomes, XY chromosomes, or both. The external genitals may be ambiguous or may appear to be female or male. This condition used to be called true hermaphroditism.

Is xy a man?
Typically, biologically male individuals have one X and one Y chromosome (XY) while those who are biologically female have two X chromosomes.
What does 1p36 mean?
1p36 deletion syndrome is caused by a deletion of genetic material from a specific region in the short (p) arm of chromosome 1. The signs and symptoms of 1p36 deletion syndrome are probably related to the loss of multiple genes in this region.
What do you mean by 1p36 deletion syndrome?

What would a 1p36 deletion look like on a karyotype?
With a 1p36 deletion, the karyotype is likely to read something like one of the following examples: 46,XY.ish del(1)(p36.3)de novo
