The NM_000231.3: c.525del p.(Phe175LeufsTer20) variant in SGCG is a frameshift variant that is predicted to introduce a premature stop codon. The resulting transcript is predicted to escape nonsense mediated decay but truncate >10% of the protein (PVS1_Strong). This variant has been detected in at least five apparently unrelated patients with autosomal recessive limb girdle muscular dystrophy, including in a homozygous state in at least four individuals (1.0 pt, PMID: 16616845, 10993494, 18285821, 10942431; ClinVar SCV001164546.1) (PM3). At least one patient with this variant displayed progressive limb girdle muscle weakness (PP4). While absent gamma-sarcoglycan protein expression has been reported in the skeletal muscle of patients with this variant, detection may be dependent on the antibody used due to the production of a truncated protein (PMID: 10993494, 16616845, 10942431). The variant has been reported to segregate with autosomal recessive LGMD in four affected family members from two families (PP1_Moderate; PMID: 10942431, ClinVar SCV001164546.1). The highest minor allele frequency of this variant is 0.0002619 (4/15274 genome chromosomes) in the Admixed American population in gnomAD v3.2.1, which is greater than the VCEP threshold (0.00009) for PM2_Supporting (criterion not met). In summary, this variant meets the criteria to be classified as Likely Pathogenic for autosomal recessive limb girdle muscular dystrophy based on the ACMG/AMP criteria applied, as specified by the ClinGen LGMD VCEP (LGMD VCEP specifications version 1.0.0; 01/08/2025): PVS1_Strong, PM3, PP4, PP1_Moderate.
