Project Baby Bear: Rapid precision care incorporating rWGS in 5 California children's hospitals demonstrates improved clinical outcomes and reduced costs of care.

Genetic disorders are a leading contributor to mortality in neonatal and pediatric intensive care units (ICUs). Rapid whole-genome sequencing (rWGS)-based rapid precision medicine (RPM) is an intervention that has demonstrated improved clinical outcomes and reduced costs of care. However, the feasibility of broad clinical deployment has not been established.

Wieacker-Wolff syndrome with associated cleft palate in a female case.

Wieacker-Wolff syndrome is a rare congenital syndrome with few reported cases in the current literature. It is traditionally described in males as an X-linked recessive disorder associated with congenital contractures of the feet, progressive neurologic muscular atrophy, and intellectual delay caused by ZC4H2 mutations. The purpose of this paper is to present a female individual with a classic phenotype and cleft palate, a previously undescribed finding in this syndrome.

Noonan syndrome with loose anagen hair associated with trichorrhexis nodosa and trichoptilosis.

We report a case of Noonan syndrome with loose anagen hair (NS/LAH), a rare variant of Noonan syndrome, with associated trichorrhexis nodosa and trichoptilosis. The mutation may be responsible for these additional hair shaft defects, revealing the importance of microscopic examination of hairs in these patients.

Menkes Disease Mimicking Child Abuse.

Althouygh Menkes disease has well-recognized neurologic, developmental, and cutaneous features, the initial presentation may resemble child abuse. We describe a 5-month-old boy with multiple fractures indicative of nonaccidental trauma who was ultimately diagnosed with Menkes disease. Copper deficiency leads to connective tissue abnormalities and may result in subdural hematomas, wormian bones, cervical spine defects, rib fractures, and spurring of the long bone metaphyses.

Prevalence of a loss-of-function mutation in the proton-coupled folate transporter gene (PCFT-SLC46A1) causing hereditary folate malabsorption in Puerto Rico.

Objective: To determine whether subjects of Puerto Rican heritage are at increased risk for a specific mutation of the proton-coupled folate transporter (PCFT) causing hereditary folate malabsorption (HFM).

Study Design: Three percent of the births in Puerto Rico in 2005, with additional regional oversampling, were screened for the prevalence of the c.1082G>A; p.

Reversible severe combined immunodeficiency phenotype secondary to a mutation of the proton-coupled folate transporter.

Hereditary folate malabsorption is a rare inborn error of metabolism due to mutations in the proton-coupled folate transporter (PCFT). Clinical presentation of PCFT deficiency may mimic severe combined immune deficiency (SCID). We report a 4-month-old female who presented with failure to thrive, normocytic anemia, Pneumocystis jirovecii pneumonia and systemic cytomegalovirus infection.

Oculo-ectodermal syndrome: is arachnoid cyst a common finding?

Oculo-ectodermal syndrome is a rare condition characterized by aplasia cutis and epibulbar dermoids. We present the case of a 6-year-old girl with oculo-ectodermal syndrome, who was found to have an arachnoid cyst by head computed tomography. This is the third case of oculo-ectodermal syndrome with arachnoid cyst reported in the literature, and suggests that arachnoid cyst may be a phenotypic feature of oculo-ectodermal syndrome.

Clinical features and management issues in Mowat-Wilson syndrome.

Mowat-Wilson syndrome (MWS) is a relatively newly described multiple congenital anomaly/mental retardation syndrome. Haploinsufficiency of a gene termed ZFHX1B (also known as SIP1) on chromosome 2 is responsible for this condition, and clinical genetic testing for MWS recently became available. The majority of reports in the literature originate from Northern Europe and Australia.

ABCA12 is the major harlequin ichthyosis gene.

Harlequin ichthyosis (HI) is the most severe form of autosomal-recessive, congenital ichthyosis. Affected infants have markedly impaired barrier function and are more susceptible to infection. Abnormalities in the localization of epidermal lipids as well as abnormal lamellar granule formation are features of HI skin.
