The first sibling was a stillborn female with a left diaphragmatic hernia (DH). Her clinical features overlapped with Fryns syndrome. The second pregnancy, a male fetus, was followed for polyhydramnios, hypoplastic mandible, mild enlargement of the fetal bladder, hydronephrosis, and rocker bottom foot deformities. He had facial features similar to his sibling and a large cleft of the secondary palate, small jaw, and secundum atrial septal defect. He underwent surgical repair of imperforate anus, intestinal malrotation, and placement of mucous fistula for biopsy positive Hirschsprung disease. An elevated alkaline phosphatase level of 1569\u2009U\/L was reported. Whole exome sequencing performed on the second child demonstrated compound heterozygosity for the <jats:italic>PIGV<\/jats:italic> gene with the p.A341E and p.A418D variants in trans. Hyperphosphatasia with mental retardation syndrome (HPMRS) is caused by mutations in <jats:italic>PIGV<\/jats:italic> and includes hyperphosphatasia as a diagnostic hallmark. Our patient exhibited hyperphosphatasia but without any storage material in his skin cells. His features remain similar to his sister's, but includes seizures and lacks diaphragmatic hernia. Until now, HPMRS and Fryns syndrome, despite overlapping features, were considered mutually exclusive as HPMRS involves hyperphosphatasia and Fryns typically exhibits DH. Recent identification of <jats:italic>PIGN<\/jats:italic> mutations associated with several cases of Fryns syndrome point to a common pathogenetic etiology involving inborn errors of the glycosylphosphatidylinositiol anchor biosynthetic pathway. A diagnosis of HPMRS should be considered when DH is encountered on prenatal ultrasound.<\/jats:p><\/jats:sec>","DOI":"10.1002\/ajmg.a.38379","type":"journal-article","created":{"date-parts":[[2017,8,17]],"date-time":"2017-08-17T13:30:35Z","timestamp":1502976635000},"page":"2776-2781","source":"Crossref","is-referenced-by-count":17,"title":["Prenatal presentation of Mabry syndrome with congenital diaphragmatic hernia and phenotypic overlap with Fryns syndrome"],"prefix":"10.1002","volume":"173","author":[{"given":"Kara K.","family":"Reynolds","sequence":"first","affiliation":[{"name":"University of Wisconsin\u2010Madison Madison Wisconsin"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jane","family":"Juusola","sequence":"additional","affiliation":[{"name":"GeneDx Gaithersburg Maryland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gregory M.","family":"Rice","sequence":"additional","affiliation":[{"name":"University of Wisconsin\u2010Madison Madison Wisconsin"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2874-8064","authenticated-orcid":false,"given":"Philip F.","family":"Giampietro","sequence":"additional","affiliation":[{"name":"Drexel University College of Medicine Philadelphia Pennsylvania"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2017,8,17]]},"reference":[{"key":"e_1_2_6_2_1","first-page":"363","article-title":"Fryns syndrome without diaphragmatic hernia.
