<div class="spaceAbove">Permanent neonatal diabetes mellitus (PNDM) is characterized by the onset of hyperglycemia within the first six months of life (mean age: 7 weeks; range: birth to age 26 weeks). The diabetes mellitus is associated with partial or complete insulin deficiency. Clinical manifestations at the time of diagnosis include hyperglycemia, glycosuria, osmotic polyuria, severe dehydration, and history of intrauterine growth deficiency. Therapy with insulin and/or oral hypoglycemic medications (in some molecular causes of PNDM) can correct the hyperglycemia and result in dramatic catch-up growth.

<div class="spaceAbove">Pontocerebellar hypoplasia type 15 (PCH15) is a severe autosomal recessive neurodevelopmental disorder characterized by congenital onset of progressive microcephaly and poor or absent psychomotor development with severely impaired intellectual development apparent from birth. Other features may include spastic quadriplegia, early-onset seizures, and chronic anemia and thrombocytopenia. Brain imaging shows pontocerebellar hypoplasia and partial agenesis of the corpus callosum (summary by et al., 2021).&#13; For a phenotypic description and a discussion of genetic heterogeneity of PCH, see PCH1A (607596).</div>

<div class="spaceAbove">Zaki syndrome (ZKS) is characterized by developmental delay, progressive microcephaly, and short stature, as well as dysmorphic features including sparse scalp hair, cupped ears, wide nose and mouth, short philtrum, and high-arched palate. Other variable features have been observed, including ocular, skeletal, cardiac, and renal anomalies (Chai et al., 2021).</div>
