Abnormal facial shape, and Atrial septal defect

Low match DIAMOND-BLACKFAN ANEMIA 4; DBA4

Diamond-Blackfan anemia (DBA) is an inherited red blood cell aplasia that usually presents in the first year of life. The main features are normochromic macrocytic anemia, reticulocytopenia, and nearly absent erythroid progenitors in the bone marrow. Patients show growth retardation, and approximately 30 to 50% have craniofacial, upper limb, heart, and urinary system congenital malformations. The majority of patients have increased mean corpuscular volume, elevated erythrocyte adenosine deaminase activity, and persistence of hemoglobin F. However, some DBA patients do not exhibit these findings, and even in the same family, symptoms can vary between affected family members (summary by Landowski et al., 2013).For a discussion of genetic heterogeneity of Diamond-Blackfan anemia, see DBA1 (OMIM ).

Low match X-LINKED INTELLECTUAL DISABILITY, SIDERIUS TYPE

X-linked intellectual disability, Siderius type is characterised by mild to borderline intellectual deficit associated with cleft lip/palate. Preaxial polydactyly, large hands and cryptorchidism are sometimes present. The syndrome has been described in seven boys from two families. Transmission is X-linked and the syndrome is caused by mutations in the PHF8 gene, localised to the p11.21 region of the X chromosome.

Low match CARDIOFACIOCUTANEOUS SYNDROME 2; CFC2

Cardiofaciocutaneous (CFC) syndrome is a multiple congenital anomaly disorder characterized by a distinctive facial appearance, heart defects, and mental retardation (summary by Niihori et al., 2006). In a phenotypic comparison of BRAF (OMIM )-positive and KRAS-positive individuals with CFC, Niihori et al. (2006) observed that patients with KRAS mutations did not have the skin abnormalities, such as ichthyosis, hyperkeratosis, and hemangioma, that were present in patients with BRAF mutation.

Low match SECOND BRANCHIAL CLEFT ANOMALY

Agnathia-otocephaly is a rare condition characterized by mandibular hypoplasia or agnathia, ventromedial auricular malposition (melotia) and/or auricular fusion (synotia), and microstomia with oroglossal hypoplasia or aglossia. Holoprosencephaly is the most commonly identified association, but skeletal, genitourinary, and cardiovascular anomalies, and situs inversus have been reported. The disorder is almost always lethal (review by Faye-Petersen et al., 2006).

Low match CONGENITAL HEART DEFECTS AND SKELETAL MALFORMATIONS SYNDROME; CHDSKM

Congenital heart defects and skeletal malformations syndrome (CHDSKM) is characterized by atrial and ventricular septal defects, with aortic root dilation in adulthood. Skeletal defects are variable and include pectus excavatum, scoliosis, and finger contractures, and some patient exhibit joint laxity. Failure to thrive is observed during infancy and early childhood (Wang et al., 2017).
