Under 38 U.S.C. § 1111, every veteran is presumed to have entered service in sound condition unless a pre-existing condition was noted on the entrance examination. If a condition was not noted at entry, the VA (or the government generally, in a service-connection dispute) must show by clear and unmistakable evidence both that the condition pre-existed service and that it was not aggravated by service in order to deny the claim on that basis. If a condition was noted at entrance, or the presumption is rebutted, a veteran can still be service-connected for aggravation of a pre-existing condition under 38 C.F.R. § 3.306, which requires showing that the underlying disability increased in severity during service beyond its natural progression. This applies to genetic and congenital conditions as well, though VA draws a distinction between congenital "defects" (generally not eligible for direct service connection, though secondary aggravation may still apply) and congenital "diseases," which can be service-connected if they worsened due to service events like a documented injury.
Building a claim like this typically requires: service treatment records showing the in-service event or diagnosis; current medical evidence, including genetic testing and specialist reports, establishing the current severity; and a medical nexus opinion explicitly linking the current disability picture to the in-service aggravation (not just confirming the genetic diagnosis exists). Each affected body system — joints, gastrointestinal, neurological — generally needs its own current diagnosis and nexus statement, and secondary service connection (38 C.F.R. § 3.310) can be used to connect complications like joint damage, esophageal scarring, or brain lesions back to a already-service-connected condition.

Filing a Supplemental Claim (VA Form 20-0995) with new and relevant evidence, or a Higher-Level Review (VA Form 20-0996) if a decision was already issued and disagreed with, restarts VA's obligation to act. A Notice of Disagreement (VA Form 10182) may also apply for Board appeals. In the appealed VA decisions in VetAid's library, spine-related appeals were vacated or remanded far more often than they were outright affirmed as denials, though these figures describe appealed cases only, not the odds of first-time approval, and appealed claims are not a random sample of all filings.
The concrete next step is to request a copy of the full claims file (C-file) and current status through eBenefits/VA.gov, then file a Supplemental Claim with a complete medical nexus opinion addressing aggravation for each condition, ideally with help from an accredited Veterans Service Officer (VSO) or claims agent.
