Severe microcephaly v2.149 PPP1R15B Eleanor Williams Added comment: Comment on publications: Previous publication entry:
26307080: In a Canadian sister and brother, born of second-cousin parents, with severe microcephaly, short stature, hypoplastic brainstem and cord, delayed myelination, and intellectual disability, Kernohan et al. (2015) identified homozygosity for a c.1972C-T mutation in PPP1R15B (R658C);26159176: In a brother and sister from a consanguineous Algerian family with microcephaly, short stature, intellectual disability, and diabetes (MSSGM2, 616817), Abdulkarim et al. (2015) identified homozygosity for the R658C substitution.

Severe microcephaly v2.147 PPP1R15B Eleanor Williams changed review comment from: Associated with Microcephaly, short stature, and impaired glucose metabolism 2 #616817 in OMIM.

PubMed: 27640355 - Mohammad et al 2016 - report WES of 2 siblings who presented with cirrhosis and required liver transplantation at age 7 and 22 months. Compound heterozygous mutations in PPP1R15B were identified. Microcephaly was also noted in both siblings. One sibling at age 4 years had head circumference at the third percentile, the other had holoprosencephaly and head circumference was below the 3rd percentile for gestational age at birth. Compound het variants in PPP1R15B; c.63G>A (p.W21*), inherited from the father, and c.674delC (p.P225LfsX10), inherited from the mother.

PubMed: 26159176 - Abdulkarim et al 2015 - report a homozygous c.1972C>T, p.R658C variant in PPP1R15B in two siblings from a consanguineous family of Algerian origin with young-onset diabetes, microcephaly, and short stature. First sibling had adult cranial perimeter: 46 cm, −4.0 SD. The sister had a similar presentation but was not available for detailed evaluation.

PubMed: 26307080 - Kernohan et al 2015 - report a consanguineous family (ethnicity not stated) with severe microcephaly, short stature, hypoplastic brainstem and cord, delayed myelination and intellectual disability in two siblings and a homozygous c.1972G>A; p.R658C variant in PPP1R15B. First sibling had head circumference of 28.5 cm (−5.0 SD) at birth, second sibling had a head circumference of head circumference of 37 cm (−6 to −7 SD) at 15 months.; to: Associated with Microcephaly, short stature, and impaired glucose metabolism 2 #616817 in OMIM.
