We report on a patient with a microdeletion of chromosome region 9q22.32q31.1 including the PTCH1 gene (human homologue of the Drosophila patched 1 gene), review the findings in the reported patients with similar array CGH findings, and highlight the non nevoid basal cell carcinoma/non-Gorlin syndrome findings at an earlier age. These are macrocephaly, neonatal hypotonia, severe psychomotor retardation with markedly delayed motor milestones and speech development, epicanthic folds, a thin upper lip, a short and wide/webbed neck, pectus excavatum and (kypho)scoliosis. These features should alert the physician to an early diagnosis of the microdeletion and allow the initiation of essential clinical management hereof.

Introduction: Nevoid basal cell carcinoma syndrome (NBCCS) is a rare autosomal dominant disorder classically associated with multiple basal cell carcinomas, odontogenic keratocysts and skeletal anomalies. However, its significant phenotypic heterogeneity often delays the diagnosis. Here, we undertake the first comprehensive characterisation of NBCCS and congenital urinary tract anomalies.

Article Synopsis
- - The study examines the rare skeletal anomaly known as bifid rib, which appears in less than 1.5% of the population and faces challenges in identification due to postmortem damage and similarity to other conditions.
- - It presents five cases of rib bifurcation from four individuals across different populations in the Kujawy region of Poland, analyzed through morphological and paleoradiological methods.
- - The research also critiques existing evidence linking bifurcated ribs to naevoid basal cell carcinoma syndrome and proposes a new way to classify this anomaly in osteological studies.

Article Synopsis
- - The study focuses on Nevoid basal cell carcinoma syndrome (NBCCS), a rare condition linked to high rates of basal cell carcinoma, potentially caused by mutations in the PTCH1 gene.
- - Researchers identified a new nonsense mutation in the PTCH1 gene in a mother and her daughter, both of whom also had ovarian mature teratomas.
- - Treatment outcomes showed persistent issues for both individuals, underscoring the complex effects of the mutation and related health challenges.

Background: Odontogenic keratocyst (OKC) is a partial manifestation of Gorlin syndrome (GS), resulting from the abnormal activation of the hedgehog signaling pathway. OKC predominantly occurs in young adults and is mostly asymptomatic at the time of initial diagnosis. As OKC is asymptomatic, GS can be challenging to diagnose in certain instances.
