Ichthyosis is a group of genetic skin disorders that present with dry, thickened, scaly, or
flaky skin. As of today, there is no cure or treatment. Doctors can only treat the dry skin
with different types of emollients to soften the scale. A deeper understanding of this
disease is required to develop better treatments. There are different types of cells and
cell-produced signals (biomarkers) that are being studied in order to help find these new
treatments. Looking at biomarkers has been successful in helping us to understand other skin
disorders better. The purpose of this study is to determine which blood and skin biomarkers
characterize ichthyosis.

Hypothesis: We predict that the biomarkers correlating with disease activity in Netherton
syndrome will be different than the biomarkers found to correlate with the lamellar and other
ichthyosis phenotype.

Objectives:

1. To define a panel of skin and blood biomarkers associated with disease activity and
pruritus in Netherton syndrome, lamellar ichthyosis, and other ichthyosis subtypes.

2. To determine if blood samples can serve as surrogates for skin immune activation and
will correlate with disease severity.

3. To determine FLG, SPINK5, TGM1, or other mutation via buccal/saliva samples in
ichthyosis subjects

4. To determine differences in alterations of epidermal lipids and proteins in the outer
stratum corneum of epidermis collected from tape strips in patients with ichthyosis
compared to the general population. There will also be a difference detected in
epidermal lipids from blood samples.

Inclusion Criteria:

- Control and ichthyosis subjects may be of either sex and must be between 1-60 years of
age at the time of enrollment

- Ichthyosis subjects include individuals with a diagnosis Netherton syndrome, lamellar
ichthyosis, or other ichthyosis subtypes

- Ichthyosis subjects should not have administered systemic immunosuppressant therapy in
the month before the study

- Ichthyosis subjects should not use topical immunosuppressants in the week before the
study

- Ichthyosis subjects should not have applied emollients to the planned biopsy sites
within 12 hours before biopsy, but can be applied elsewhere

- Controls may have no inflammatory disease, atopy, or obvious xerosis (urticaria, food
allergy, allergic rhinitis or conjunctivitis, asthma)

- Controls for skin sampling may have no observable abnormality in the sampled skin and,
to further assure the normality of the "normal" skin edges, must not have evidence of
inflammation or epidermal change in the lesion to be surgically removed

- Subjects and guardians of minors must sign the approved IRB consent form(s) prior to
initiation of the study protocol

Exclusion Criteria:

- Subjects who are unable to give informed consent or assent

- Subjects who administered anti-inflammatory systemic and topical therapy or emollients
that do not comply with inclusion criteria prior to blood and biopsy sampling

- Subjects whose main diagnosis is deemed unsafe by the study investigator for study
participation
