Hypothesis
To screen the visual system homebox 1 (VSX1) gene in Saudi Arabian keratoconus patients.
Conclusion
In our keratoconus cohort, no pathogenic VSX1 mutation(s) were identified.
Supporting Evidence
- Five nucleotide changes were found in the VSX1 gene, but none were pathogenic.
- Three of the changes were non-coding and two were synonymous-coding.
- 56.4% of keratoconus cases were sporadic, while 34.6% were autosomal recessive.
Takeaway
The study looked at a gene called VSX1 in people with a condition called keratoconus, and they found that this gene didn't have any harmful changes in these patients.
Methodology
The entire coding region and exon-intron boundaries of the VSX1 gene were sequenced in 55 keratoconus patients and 50 healthy controls.
Limitations
The study only included patients from a specific region and may not represent all populations.
Participant Demographics
55 unrelated Saudi keratoconus patients (24 males and 31 females) with a mean age of 28.9 years.
