Microphthalmos associated with other systemic anomalies (e.g., in trisomy 13 and congenital rubella). To assess DNA purity, a Spectrophotometer NanoDrop 2000 was used to evaluate ratio of the absorbance at 260/280 nm (average of 1.90 for all samples) and at 260/230 nm (average of 1.91 for all samples). Sequencing data were processed and analyzed using SOPHiA pipelines and DDM software (Switzerland), and the genetic variant calls were performed against the reference sequence of hg19 from the University of California Santa Cruz (UCSC) Genome Browser. Proband was examined at 3 months old and had an unremarkable gestational and peripartum history.

Pediatric cataract is a phenotypically and genetically heterogeneous disorder and inherited traits showed interfamily and intrafamily variability [11]. Ophthalmological examination revealed aphakia with a shallow anterior chamber and high intraocular pressure. Histologically, the eye ranges from essentially normal in nanophthalmos to rudimentary in clinical anophthalmos, and all degrees of abnormality in between.

It can develop to complete cataract. The variants pathogenicity is also supported by 11 of the 12 predictors, except PrimateAI. Many people with this condition have delayed development or intellectual disability ranging from mild to severe. Is this normal for a cat with this condition? Seventy percent of pediatric cataract are isolated [1], and, as expected, most of the CRYBB3 mutations reported in the Cat-Map are also isolated [6]. No clinical signs of upper respiratory, urinary, or gastrointestinal tract disease were observed during the approximately 3.5-year follow-up period.

The most common sign ofstrabismusin cats is that the cat lookscross-eyedand is otherwise normal.

Sir, The congenital abnormality of microphthalmia has been variously described as rare in cats (1) and not rare in kittens (2). Early forms of PRAs are evident from about 2 years of age, whereas the late forms may become evident as late as ten years of age or even later. Pediatr. Congenital Aplasia/hypoplasia of the tear canals/canuliculi: Symptoms are excessive tearing usually without any signs ocular discomfort. By licking you, other cats, or even other pets, your cat is creating a social bond. To eliminate this mutation from breeding lines and to avoid the potential of producing affected pups, breeding known carriers to each other is not recommended. Graduated from ENSAT (national agronomic school of Toulouse) in plant sciences in 2018, I pursued a CIFRE doctorate under contract with SunAgri and INRAE in Avignon between 2019 and 2022.
