He developed calf muscle pain and recurrent falls on walking for 7 years. He had atrophy of calves (medial gastrocnemius more than lateral) along with weakness of hip extensor, adductors and knee flexors and normal upper limb power, resembling Miyoshi myopathy. Serum creatine kinase ranged from 3524 to 6531\u2005U\/L. Muscle MRI showed selective atrophy of gluteus maximus, quadriceps femoris, semimembranosus and gastrocnemius with sparing of rectus femoris, gracilis and sartorius. Muscle biopsy done elsewhere and reported to show dystrophic features and immunohistochemistry showed positive staining for dystrophins and sarcoglycans. Clinically the possibility of LGMDR2\/Dysferlinopathy, was considered and whole exome sequencing was done which revealed a novel homozygous pathogenic nonsense premature termination codon (PTC) variant (NM_022361.5) c.316C\u2009&gt;\u2009T (NP_079130.2:) p.Arg106Ter) in exon 2 of\n                      <jats:italic toggle=\"yes\">POPDC3<\/jats:italic>\n                      gene.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>\n                      This is the first report of POPDC3- LGMDR26 from India detected among a large cohort (461 genetically confirmed cases).\n                      <jats:italic toggle=\"yes\">POPDC3<\/jats:italic>\n                      gene variations should be considered in distal onset LGMDs with markedly elevated serum creatine kinase levels.\n                    <\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/22143602251370589","type":"journal-article","created":{"date-parts":[[2025,9,30]],"date-time":"2025-09-30T19:44:59Z","timestamp":1759261499000},"page":"817-823","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["An interesting report of POPDC3 limb girdle muscular dystrophy R26 from India"],"prefix":"10.1177","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8362-7380","authenticated-orcid":false,"given":"Dipti","family":"Baskar","sequence":"first","affiliation":[{"name":"Department of Neurology, National Institute of Mental Health and Neuro Sciences (NIMHANS), Bengaluru, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8879-6001","authenticated-orcid":false,"given":"Kiran","family":"Polavarapu","sequence":"additional","affiliation":[{"name":"Children's Hospital of Eastern Ontario Research Institute, University of Ottawa and Division of Neurology, Department of Medicine, The Ottawa Hospital, Ottawa, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0037-5374","authenticated-orcid":false,"given":"Ananthapadmanabha","family":"Kotambail","sequence":"additional","affiliation":[{"name":"Department of Human Genetics, National Institute of mental Health and Neuro Sciences (NIMHANS), Bengaluru, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8565-1624","authenticated-orcid":false,"given":"Gautham","family":"Arunachal","sequence":"additional","affiliation":[{"name":"Department of Human Genetics, National Institute of mental Health and Neuro Sciences (NIMHANS), Bengaluru, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4492-7783","authenticated-orcid":false,"given":"Seetam Kumar","family":"Tumulu","sequence":"additional","affiliation":[{"name":"Department of Neuro Imaging and Interventional Radiology, National Institute of Mental Health and Neuro Sciences (NIMHANS), Bengaluru, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7929-5635","authenticated-orcid":false,"given":"Madhulika","family":"Kotra","sequence":"additional","affiliation":[{"name":"Department of Neurology, National Institute of Mental Health and Neuro Sciences (NIMHANS), Bengaluru, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0002-3403-4447","authenticated-orcid":false,"given":"Darshan","family":"Gowda","sequence":"additional","affiliation":[{"name":"Department of Neurology, National Institute of Mental Health and Neuro Sciences (NIMHANS), Bengaluru, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9791-3639","authenticated-orcid":false,"given":"Atchayaram","family":"Nalini","sequence":"additional","affiliation":[{"name":"Department of Neurology, National Institute of Mental Health and Neuro Sciences (NIMHANS), Bengaluru, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0629-9221","authenticated-orcid":false,"given":"Seena","family":"Vengalil","sequence":"additional","affiliation":[{"name":"Department of Neurology, National Institute of Mental Health and Neuro Sciences (NIMHANS), Bengaluru, India"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2025,9,30]]},"reference":[{"key":"e_1_3_2_2_2","first-page":"207","article-title":"LGMD.
