Bilateral cryptophthalmos with overlapping features of Manitoba oculo-tricho-anal (MOTA) syndrome and Fraser syndrome 2.

A male baby with bilateral cryptophthalmos without eyebrows, distorted anterior hairline, bifid nasal tip, low-set ears, hypertelorism and low anorectal anomaly who was phenotypically diagnosed with Manitoba oculo-tricho-anal syndrome (mutation in FREM1 gene) had an overlapping genotypic diagnosis of autosomal recessive Fraser syndrome 2 because of the presence of a closely related mutation in FREM2 This heterozygous variant was likely to be sporadic. Another mutation was identified in the CEP85L gene indicating lissencephaly 10. This genetic condition has abnormal gyri pattern in the occiput area. This form of lissencephaly is characterised by phenotypic heterogeneity whereby some patients have only mild mental retardation, while others have a very complex clinical picture.In conclusion, this rare condition with the overlap of genetics between several conditions highlights the need for genetic testing even in an low middle income country (LMIC).

Type II Pfieffer misdiagnosed as Crouzon syndrome with additional features of supernumerary teeth and localized symmetrical gigantism: a case report.

BACKGROUND: Pfieffer syndrome is among the syndromes seen in the recognized variant of the FGFR2 gene. There are several conditions related to this variant and a very closely related condition is Crouzon syndrome. This case is important to report because the neonate was a delayed referral from another region, without clear counseling and information on the gravity of situation. We describe additional features , not previously described in Pfieffer or Crouzon syndrome, supernumerary teeth and localized symmetrical gigantism of thumbs and great toes on both sides. That a genetic testing is essential to further manage and counsel to avoid lost opportunities for future births. Several cases are seen in this unit annually, and there is need for a more consolidated and comprehensive counseling and genetic testing. Once early diagnosis is done and the case is recognized to be untreatable, it was avert the need to refer. CASE PRESENTATION: A 2-week-old male African neonate referred from outside the region, presented with massive proptosis soon after delivery, with signs of pan-ophthalmitis and neonatal sepsis. The infant had additional multiple malformations and features initially diagnosed as Crouzon syndrome , but later confirmed after genetic testing to be Type II Pfieffer syndrome. A through clinical evaluation and genetic testing would prevent undue referral to a tertiary center, or if needed, the baby should have been referred much earlier. The uniqueness of this case is the presence of supernumerary teeth. CONCLUSION: A complicated, difficult to remedy case, referred to tertiary center, investigated, and sent back home with no significant intervention. Genetic test confirmed the typical findings of Pfieffer Type II. Presented for describing additional unique features of supernumerary teeth and localized gigantism and ethical challenges in management.
