Abstract
INTRODUCTION AND IMPORTANCE Neurofibromatosis type I (NF1, OMIM: 162200) is a benign, autosomal dominant, tumorigenic predisposing syndrome with variable manifestations. Both neurofibromatosis and soft tissue sarcomas are associated with the formation of hematomas. Moreover, skeletal manifestations of NF1 include focal or generalized forms and expansive or infiltrative growth types. CASE PRESENTATION A 19-year-old NF1 female patient presented with an expanding post-traumatic facial hematoma that resembled a soft-tissue tumor at initial presentation. A congenital neck mass was noted ipsilateral to her craniofacial skeletal deformities. Multiple imaging modalities were used to aid diagnosis, and urgent surgical intervention of the expanding facial lesion was performed. Her neck lesion and skeletal deformities were monitored, and her recovery was uneventful at 1-year follow-up, with no progression. CLINICAL DISCUSSION A palpable, non-pulsatile soft tissue mass is a common clinical presentation with a diverse differential diagnosis. Despite the low incidence of post-traumatic vascular injuries and lesions in the maxillofacial region, neurofibromatosis-associated vasculopathy remains an underestimated and serious manifestation of NF1. The reported zygomatic arch deformity is believed to be unique. However, the NF1 tumor-associated skeletal malformations are not linearly related. CONCLUSION NF1 is a multisystem disorder necessitating an early multidisciplinary team approach. Minimal intervention can help convert an emergent operation into an urgent one and preclude the need for major surgery. The case illustrated a rare example of simultaneous affection of soft tissue and jaw bones in NF1 patients.

Abstract
Stroke causes significant disability and is a common cause of death worldwide. Previous studies have estimated that 1%-5% of stroke is attributable to monogenic etiologies. We set out to assess the utility of clinical exome sequencing (ES) in the evaluation of stroke. We retrospectively analyzed 124 individuals who received ES at the Baylor Genetics reference lab between 2012 and 2021 who had stroke as a major part of their reported phenotype. Ages ranged from 10 days to 69 years. 8.9% of the cohort received a diagnosis, including 25% of infants less than 1 year old; an additional 10.5% of the cohort received a probable diagnosis. We identified several syndromes that predispose to stroke such as COL4A1-related brain small vessel disease, homocystinuria caused by CBS mutation, POLG-related disorders, TTC19-linked mitochondrial disease, and RNASEH2A associated Aicardi-Goutieres syndrome. We also observed pathogenic variants in NSD1, PKHD1, HRAS, and ATP13A2, which are genes rarely associated with stroke. Although stroke is a complex phenotype with varying pathologies and risk factors, these results show that use of exome sequencing can be highly relevant in stroke, especially for those presenting <1 year of age.
