Pathogenic variants of SP-C, which cause various lung diseases with varying ages of onset, are inherited in an autosomal dominant manner or appear de novo as new mutations. We present a case of fatal respiratory failure in a female infant. Genetic analysis confirmed an intragenic deletion encompassing exon 4 in the SFTPC gene, starting in the intron region before exon 4, extending into the exon 4 and portion, in a heterozygous state. This variant, c.325-47_374del, in the SFTPC gene has not yet been described in the literature. Despite an experimental therapy with hydroxychloroquine, the baby girl died on Day 162.

Glycerol kinase deficiency (GKD) is an X-linked recessive disorder due to () gene mutations resulting in hyperglycerolermia, hyperglyceroluria, and "pseudohypertriglyceridemia." In vivo glycerol metabolism has not been assessed in GKD. A 62-year-old man with suspected GKD and his extended family underwent whole exome sequencing and fasting blood work with two modes of lipid measurements: (1) standard lipase-based methodology and (2) nuclear magnetic resonance (NMR).

SMARCB1-deficient sinonasal adenocarcinoma is a rare variant of SWI/SNF-deficient malignancies with SMARCB1 loss and adenocarcinoma features. More than 200 high-grade epithelial sinonasal malignancies were retrieved. A total of 14 cases exhibited complete SMARCB1 (INI1) loss and glandular differentiation.
