Market Driver - Rising prevalence of somatic mutations in the TGM1 gene, leading to increased cases of Lamellar Ichthyosis.

The rising prevalence of somatic mutations in the TGM1 gene is significantly contributing to the increased incidence of Lamellar Ichthyosis cases around the world. Lamellar Ichthyosis is a rare genetic skin disorder characterized by dry, thickened skin with large, dark plates that can resemble scales. It is caused due to mutations in the TGM1 gene which encodes the transglutaminase-1 enzyme involved in formation of the skin barrier.

Recent scientific studies have found a growing number of patients diagnosed with Lamellar Ichthyosis carrying de novo or somatic mutations in the TGM1 gene rather than the more commonly reported inherited mutations. Somatic mutations occur post-fertilization in non-germline cells of the developing embryo and give rise to mosaicism where both normal and mutated cells co-exist in the individual. They have been found to account for up to 30-40% of all disease-causing TGM1 mutations in some studies. As somatic mutations are not inherited but arise fresh during embryo development, they are leading to more sporadic cases without any family history of the disease.

With advancements in next-generation sequencing technologies and whole exome studies, more asymptomatic individuals are being identified as mosaic for TGM1 mutations with a subpopulation of mutated cells in the skin. It is believed that with widespread application of powerful genomic tools, the identified prevalence of somatic mutations linked to Lamellar Ichthyosis will continue rising going forward. The growing awareness about the association of newly arising somatic mutations with Lamellar Ichthyosis is an important driver as it is helping more atypical cases and asymptomatic individuals get diagnosed that otherwise would have been missed. This factor is directing more patients towards seeking treatment and care, thereby serving to increase the potential market scope over time.

Lamellar Ichthyosis (LI) is a severe inherited skin disorder characterized by dark, thick, scaly skin. Prescribers follow a stepwise treatment approach based on the stage of LI.For mild cases, topical emollients like cetaphil lotion are prescribed to moisturize skin. As LI progresses, topical retinoids become critical. Tazorac cream 0.1%, a second-generation topical retinoid, is often the first line treatment at this stage due to its effectiveness in reducing scaly skin. For moderate-severe LI, topical anthralin or calcipotriene can be addded to the regimen.

If topical treatments are insufficient, prescribers may supplement with systemic retinoids. Acitretin capsules under brand names Soriatane or Neotigason are frequently prescribed as the second line treatment. Starting at a low dose of 25mg daily, acitretin helps control skin shedding and hyperkeratosis. For patients unresponsive to acitretin, prescribers occasionally use isotretinoin (Accutane) as a third line treatment option, with monitoring for side effects.

Prescribers also consider individual factors like co-morbidities, compliance, skin care routines and response to previous therapies to determine the most suitable treatment plan. Persistent education on proper application of topicals and regular follow-ups are important to achieve optimal management of LI over the long-term.

Lamellar Ichthyosis (LI) is a rare genetic skin disorder characterized by thick, dry scaling of the skin. Treatment focuses on managing symptoms which vary depending on the severity and stage of LI. Mild cases are often treated with topical moisturizers and medications.

For moderate to severe LI, retinoids are the first line of treatment. Isotretinoin (Claravis) taken orally is highly effective at reducing scale and improving skin texture. It works by increasing shedding of scaling skin. For children, topical tretinoin (Retin-A) cream is often used initially due to fewer side effects. Long-term use is required to maintain results.

For patients not responding well to retinoids, second line options include topical calcipotriene (Dovonex) or topical steroids. Calcipotriene works to normalize skin cell maturation and shedding, while steroids reduce scaling and inflammation. Combination therapy with calcipotriene and a low potency steroid provides added benefits over monotherapy.

Retinoids are chosen as first line due to their proven efficacy in large clinical studies. They efficiently reduce the hyperkeratotic scaling that is the hallmark of LI. Topical therapies have more localized effects and potential side effects, so they are often tried before or after retinoid therapy depending on case severity and responsiveness. Later stage LI may require maintenance retinoid dosing or addition of second line agents to adequately control symptoms.
