Frozen shoulder, also known as adhesive capsulitis, is a condition characterized by stiffness and pain in your shoulder joint. Signs and symptoms typically begin gradually, worsen over time and then resolve, usually within one to three years. Your risk of developing frozen shoulder increases if you're recovering from a medical condition or procedure that prevents you from moving your arm â such as a stroke or a mastectomy.
The data itself shows that of the 14 haplogroups found in the Sephardic Jewish community, M172, Haplogroup J2 is the most frequent haplogroup overall, representing 25% of this population group. This was followed closely by M267, Haplogroup J1 which represented 22% of the total. In the Iberian Peninsula, M172, Haplogroup J2 was most frequent in the south, 15% in Southern Portugal, 14% in Western Andalusia and 12% in Extremadura.
R1b1a2, the most common western European haplogroup, arose 4,000 to 8,000 years ago in southwest Asia and later spread to Europe. Haplogroup composition of the ancient Iberians was very similar to that found in the modern Iberian Peninsula populations, suggesting a long-term genetic continuity since pre-Roman times.-chromosome analysis had suggested Paleolithic ancestry among populations in the Iberian Peninsula and that Iberia may have played a role in the re-population of western Europe after the last glaciation.
