H Syndrome, Histiocytosis-lymphadenopathy plus syndrome, or PHID, is a condition that may or may not be considered an intersex condition, or it may be considered a condition that comes with intersex traits, depending on who you ask.
Those with this condition tend to have hypogonadism, darker than usual skin (hyperpigmentation), more hair growth than usual (hypertrichosis), hearing loss, heart anomalies, low height, hyperglycemia, hallux valgus, and hepatosplenomegaly (enlarged spleen and liver).
Causes
This condition is caused by a mutation within the SLC29A3 gene, which is a gene that helps encode important proteins within the human body.
History
This condition was first described in 1998.
Etymology
This condition was named "H Syndrome" due to most of the symptoms starting with the letter H.
