rs61735045, also known as c.1588G>A, p.Gly530Ser and G530S, is a variant in the COL5A1 gene on chromosome 9. Two papers published in 2000 and 2002 proposed that carrying one copy of an rs61735045(A) allele worsened symptoms of Ehlers-Danlos syndrome(EDS) in those who had it due to a causative mutation elsewhere, and that carrying two copies would cause EDS. More recent analyses have concluded that the rs61735045(A) allele is quite likely to actually be benign. A 2009 publication found that the frequency of the 530S allele was similar (about 5%) in all groups of people they studied, whether healthy or EDS-affected. Furthermore, the predicted homozygote minor frequency of 1 in 400 people is much higher than that of classical EDS. More recently, ExAC analysis shows an allele frequency of 3.5%, and a minor homozygote frequency of about 1 in 1000, which is still an order of magnitude or more higher than the estimated EDS incidence, incidating that either this allele is benign or the penetrance of even a double mutation is quite low. Additionally, as of 2014, two labs are reporting in ClinVar this variant as benign. In summary, the majority of current evidence indicates that the rs61735045 variant is likely to be benign.
