What the study found

Who was studied 33,483 Japanese ancestry individuals.

The effect Each copy of the G allele shifted the measure 0.103 lower (95% confidence interval 0.074-0.132); p = 2 × 10−16.

How common The G allele had a frequency of about 9% in the people studied.

Where it sits Chromosome 2, band 2q37.1 — in an intron of PRSS56.

What ClinVar records

Classification Benign for Isolated microphthalmia 6, PRSS56-related disorder; criteria provided, multiple submitters, no conflicts (2 of 4 stars, 4 submitters), last evaluated 2025-10-12. ClinVar record 707140 NM_001195129.2(PRSS56):c.205+10C>G

What this is ClinVar's aggregate record for this position (as of its 2026-10-12 release), not a result about you. A classification describes the variant against the condition named, as laboratories submitted it. Whether a person carries this variant, and what that would mean for them, is a question for a clinical test and a genetic counsellor.

What each result means

C/C No copy of the version the research linked to Axial length. This is the starting point the study compared everyone against.
C/G One copy of the version the research linked to Axial length. That is a smaller link than two copies.
G/G Two copies of the version the research linked to Axial length. That is the strongest link of the three results. A link in a study is not a diagnosis.

Questions about rs77311538

What is rs77311538?

rs77311538 is a single position in the genome, in or near the PRSS56 gene. Published research associates it with axial length. A single variant does not decide an outcome — it shifts a probability, and for most common variants the shift is small.

Does having rs77311538 mean I will get this?

No. Common variants like this one move a probability slightly and, on their own, rarely decide anything about one person. Nothing on this page is a diagnosis, and health decisions should be made with a clinician who can see your whole picture.

Where does the information about rs77311538 come from?

GWAS Catalog, Ophthalmology science 2022, PMID:36246171. Every variant on MyGeneLog comes from public primary sources and is published with its citation and the date it was checked.
