Purpose: Somatic activating variants in the PI3K-AKT pathway cause vascular malformations with and without overgrowth. We previously reported an individual with capillary and lymphatic malformation harboring a pathogenic somatic variant in PIK3R1, which encodes three PI3K complex regulatory subunits. Here, we investigate PIK3R1 in a large cohort with vascular anomalies and identify an additional 16 individuals with somatic mosaic variants in PIK3R1.

Article Synopsis
  • Next-generation sequencing is useful for finding somatic mosaicism in diseases, but identifying low-level mosaic variants is challenging.
  • The new Position-Based Variant Identification (PBVI) method enhances the detection of single nucleotide mosaic variants, achieving over 85% sensitivity at low variant levels.
  • PBVI effectively identified pathogenic variants in 17 out of 26 individuals with somatic overgrowth disorders, demonstrating its potential for research and diagnostics.

Individuals with orofacial asymmetry due to mucosal overgrowths, ipsilateral bone and dental aberrations with perineurial hyperplasia and/or perineuriomatous pseudo-onion bulb proliferations, comprise a recognizable clinical entity. In this article, we describe three individuals with this clinical entity and mosaic variants c.3140A>G (p.

Background: A single variant in (c.471+2T>A), the gene encoding N-acetyltransferase 10, has been associated with Lenz microphthalmia syndrome. In this study, we aimed to identify causative variants in families with syndromic X-linked microphthalmia.
