Invitae RCV001237031 SCV001409778 likely pathogenic Autosomal recessive limb-girdle muscular dystrophy type 2O; Muscular dystrophy-dystroglycanopathy (congenital with intellectual disability), type B3 2019-10-14 criteria provided, single submitter clinical testing This variant results in the deletion of exon 3 and part of exon 4 in addition to an insertion of three nucleotides (c.121-67_265delinsTAG) in the POMGNT1 gene. It is expected to disrupt RNA splicing and likely results in an absent or disrupted protein product. This variant has not been reported in the literature in individuals with POMGNT1-related conditions. Loss-of-function variants in POMGNT1 are known to be pathogenic (PMID: 19299310, 20816175, 21447391, 26908613, 27391550). In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic.
