| Palmoplantar Keratoderma and Erythrokeratoderma v1.2 | EGFR |
chirag patel gene: EGFR was added gene: EGFR was added to Palmoplantar Keratoderma and Erythrokeratoderma. Sources: Literature Mode of inheritance for gene: EGFR was set to MONOALLELIC, autosomal or pseudoautosomal, NOT imprinted Publications for gene: EGFR were set to 41533385 Phenotypes for gene: EGFR were set to Wooly hair-palmoplantar keratoderma syndrome, MONDO:0014492; Acanthosis nigricans MONDO:0007035 Mode of pathogenicity for gene: EGFR was set to Other Review for gene: EGFR was set to AMBER Added comment: 3 unrelated individuals presenting with widespread acanthosis nigricans, woolly hair, palmoplantar keratoderma and pulmonary nodules (consistent with atypical adenomatous hyperplasia). They all had the same heterozygous variant in EGFR (p.L858R). Two were shown to be de novo, and one was in post‑zygotic mosaic state. Patient‑cell assays show increased EGFR‑signalling supporting a gain of function mechanism. Therapy with an EGFR inhibitor in the 2 patients with germline variants showed marked improvement in skin and lung manifestations. Sources: Literature |

| Palmoplantar Keratoderma and Erythrokeratoderma v0.94 | PERP | Zornitza Stark edited their review of gene: PERP: Added comment: Four families reported with heterozygous variants and Olmsted syndrome-2 (OLMS2), which is characterised by mutilating hyperkeratotic skin lesions, primarily on the palms and soles, but also extending onto dorsal surfaces of the hands and feet and distal extremities. The lesions are progressive, becoming thicker with verrucous fissures on the palms and soles over time. In addition, affected individuals exhibit perioral hyperkeratosis, and may have lesions around other orifices as well, such as the nostrils, perineum, and anus. Most patients also have hyperkeratotic nails and light-colored woolly hair. Two families reported with bi-allelic variants and Erythrokeratodermia variabilis et progressiva-7 (EKVP7), which is characterised by palmoplantar keratoderma that extends to the dorsal surface of the hands and feet (transgrediens), as well as erythematous annular skin lesions. Pruritis, woolly hair, and dystrophic nails may also be present.; Changed rating: GREEN; Changed publications: 31898316, 30321533, 31361044; Changed phenotypes: Olmsted syndrome 2, MIM# 619208, Erythrokeratodermia variabilis et progressiva 7, MIM# 619209; Changed mode of inheritance: BOTH monoallelic and biallelic, autosomal or pseudoautosomal | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

chirag patel gene: PERP was added gene: PERP was added to Palmoplantar Keratoderma and Erythrokeratoderma. Sources: Literature Mode of inheritance for gene: PERP was set to BIALLELIC, autosomal or pseudoautosomal Publications for gene: PERP were set to PMID: 31898316 Phenotypes for gene: PERP were set to Erythrokeratoderma, no OMIM # yet Review for gene: PERP was set to RED Added comment: One extended multiplex consanguineous family with Erythrokeratoderma (striking similarity to that observed in Perp −/− mice), and a novel homozygous variant (c.466G>A; p.Gly156Arg) in PERP that fully segregated with the phenotype. Functional analysis of patient‐ and control‐derived keratinocytes revealed a deleterious effect of the identified variant on the intracellular localization of PERP. A previous report showed that PERP mutation causes a dominant form of keratoderma but a single patient in that report with a homozygous variant in PERP suggests that recessive inheritance is also possible.
