BIDS syndrome
Encyclopedia
BIDS syndrome, also called nonphotosensitive trichothiodystrophy 1 (TTND1), Amish brittle hair brain syndrome and hair-brain syndrome, is an autosomal
recessive genodermatosis
similar to IBIDS syndrome
but without the ichthyosiform changes. BIDS is characterized by brittle hair, intellectual impairment, decreased fertility, and short stature.
It is associated with C7ORF11
.
Autosome
An autosome is a chromosome that is not a sex chromosome, or allosome; that is to say, there is an equal number of copies of the chromosome in males and females. For example, in humans, there are 22 pairs of autosomes. In addition to autosomes, there are sex chromosomes, to be specific: X and Y...

C7orf11
TTD non-photosensitive 1 protein is a protein that in humans is encoded by the C7orf11 gene.. Patients with an inherited defect in both alleles of the gene suffer from trichothiodystrophy , a disease hallmarked by brittle hair and nails and usually by developmental difficulties as well...
