Ophthalmic findings in patients with autosomal recessive lamellar ichthyosis due to TGM1 mutations in an isolated population. Int Ophthalmol 2023; 43:3659-3665. [PMID: 37542530 PMCID: PMC10504104 DOI: 10.1007/s10792-023-02774-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/03/2023] [Accepted: 06/22/2023] [Indexed: 08/07/2023]
Abstract
PURPOSE To describe the ocular clinical characteristics of a group of Mexican patients with lamellar ichthyosis (LI) arising from TGM1 pathogenic variants. METHODS Ophthalmological exploration, pedigree analysis and genetic screening were performed in patients with an established clinical diagnosis of lamellar ichthyosis from families located in a small community in the Southeast of Mexico. RESULTS Nine patients with LI in five families were identified. There were six affected females. All patients (9/9) demonstrated eye lid abnormalities with eight patients showing lid margin abnormalities. Madarosis was present in only three individuals and corneal scarring was documented in two. All nine individuals carried biallelic TGM1 variants, either homozygously or as compound heterozygous. CONCLUSION Ocular anomalies are common in individuals with TGM1-related LI. The occurrence of a variety of private or rare mutations hampers the identification of a genotype-phenotype correlation for ocular anomalies in this disorder.

Abstract
Harlequin ichthyosis is a rare and severe genetic skin disorder that occurs
within the developing foetus. Harlequin ichthyosis is the most severe and
devastating form of autosomal recessive congenital ichthyoses. It is caused by
mutations in the lipid transporter adenosine triphosphate binding cassette A 12.
Here, we reported a case of harlequin ichthyosis with no family history. No
abnormalities were detected in prenatal sonography. A 24-year-old pregnant woman
with premature rupture of membrane and labour pain was referred to a hospital in
Shoushtar city, Iran. The mother delivered a male baby with harlequin
ichthyosis. The infant baby died on the 5th day. Harlequin ichthyosis is
associated with adenosine triphosphate binding cassette A 12 gene mutation;
therefore, genetic screening and counselling for susceptible parents should be
taken into account. Prenatal diagnosis of harlequin ichthyosis principally via
sonographic techniques is important in managing the disorder.

Abstract
Harlequin ichthyosis (HI) is a life-threatening genetic disorder that largely affects the skin of infants. HI is the most severe form of the autosomal recessive disorder known as ichthyosis. It is caused by mutations in the A12 cassette (lipid-transporter adenosine triphosphate-binding cassette A12). Neonates affected by this disease are born with specific morphological characteristics, the most prominent of which is the appearance of platelet keratotic scales separated by erythematous fissures. The facial features include eclabium, ectropion, a distinct flattened nose, and dysplastic ears. A common finding among those with HI is impaired skin barrier function. The purpose of the present narrative review is to assess the most recent literature regarding the management of HI. Emphasis is given to surgical management and consultation, to the indications for timing and surgical intervention, to the risks that are presented with surgery, and to the details of the surgical procedure itself. Management of HI requires a multidisciplinary team of experts, and specific guidelines are needed in order for the risks to be minimized and viability to be increased.
