One of these conditions is <strong>globozoospermia<\/strong>, characterized by the rounded shape of the sperm heads due to the absence of acrosome, representing 0.1% of all cases of male infertility. Although assisted reproduction allows many couples with fertility problems to conceive, it is important to know the genetic cause for improving the outcome of the reproductive treatment and determining the risk of future progeny.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-20721 size-full\" src=\"https:\/\/idibell.cat\/en\/wp-content\/uploads\/sites\/2\/2022\/06\/NO-S-Larriba_GWAS-Imatge2.jpg\" alt=\"\" width=\"1103\" height=\"287\" srcset=\"https:\/\/idibell.cat\/en\/wp-content\/uploads\/sites\/2\/2022\/06\/NO-S-Larriba_GWAS-Imatge2.jpg 1103w, https:\/\/idibell.cat\/en\/wp-content\/uploads\/sites\/2\/2022\/06\/NO-S-Larriba_GWAS-Imatge2-300x78.jpg 300w, https:\/\/idibell.cat\/en\/wp-content\/uploads\/sites\/2\/2022\/06\/NO-S-Larriba_GWAS-Imatge2-1024x266.jpg 1024w, https:\/\/idibell.cat\/en\/wp-content\/uploads\/sites\/2\/2022\/06\/NO-S-Larriba_GWAS-Imatge2-768x200.jpg 768w\" sizes=\"auto, (max-width: 1103px) 100vw, 1103px\" \/><\/p>\n<p>Now a group of researchers from the <strong>Puigvert Foundation<\/strong> (Dr. Llu\u00eds Bassas and Dr. Olga L\u00f3pez-Rodrigo) and the <strong>University of Granada<\/strong> (Dr. Lara Bossini-Castillo and Dr. David Carmona), led by the IDIBELL team of <strong>Dr. Sara Larriba<\/strong> shows the usefulness of genome-wide association studies (GWAS) from large-scale genotyping data as an advantageous strategy to identify the molecular cause of globozoospermia in two siblings from a non-consanguineous family.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignleft wp-image-20719 size-full\" src=\"https:\/\/idibell.cat\/en\/wp-content\/uploads\/sites\/2\/2022\/06\/NO-S-Larriba_GWAS-Imatge3.jpg\" alt=\"\" width=\"402\" height=\"719\" srcset=\"https:\/\/idibell.cat\/en\/wp-content\/uploads\/sites\/2\/2022\/06\/NO-S-Larriba_GWAS-Imatge3.jpg 402w, https:\/\/idibell.cat\/en\/wp-content\/uploads\/sites\/2\/2022\/06\/NO-S-Larriba_GWAS-Imatge3-168x300.jpg 168w\" sizes=\"auto, (max-width: 402px) 100vw, 402px\" \/>This genetic study allowed the identification of the first case in globozoospermic patients of compound heterozygosis for two different mutations in the <em>DPY19L2<\/em> gene. In other words, these patients have both alleles of the gene-altered by different mutations. This suggests that mutations in <em>DPY19L2<\/em> could be responsible for the cases of globozoospermia in non-consanguineous families for which the molecular cause is still unknown.<\/p>\n<p><strong>Dr. Sara Larriba<\/strong>, a principal investigator of the IDIBELL human molecular genetics research group and leader of the work, concludes: &#8220;<em>The GWAS-genotyping technique could be a much more cost-effective alternative than the complete genome sequencing, especially for those pathogenic variants that complete sequencing cannot detect, such as those related to segmental duplications or pseudogenes, as occurs in the DPY19L2 gene<\/em>\u201d. This strategy can be applied in similar contexts in the genetic study of families affected by other congenital diseases.<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p><em>The Bellvitge Biomedical Research Institute (IDIBELL) is a biomedical research center created in 2004.
