The NM_000023.4: c.614C>A variant in SGCA is a missense variant predicted to cause substitution of proline by histidine at amino acid 205, p.(Pro205His). This variant has been detected in at least five individuals with limb-girdle muscular dystrophy, including in a homozygous state in two patients, one with reported consanguinity (0.75 pts; PMID: 35948506; LOVD Individual #00468440). Three patients were presumed compound heterozygous for the variant and a second pathogenic variant (c.409G>A p.(Glu137Lys), 0.5 pts x2, PMID: 31069529, 9032047; c.269A>G p.(Tyr90Cys), 0.5 pts, GRASP-LGMD Consortium internal data communication). (PM3_Strong) At least one patient heterozygous for this variant and a second diagnostic SGCA variant displayed progressive limb girdle muscle weakness and absent alpha-sarcoglycan protein expression, which is highly specific for SGCA-related LGMD, but SGCD was not included in the genetic analysis (PP4; PMID: 9032047). The upper bound of the 95% confidence interval of the Grpmax variant allele frequency in gnomAD v4.1.1 is 0.0001404 (5/74894 African/African-American alleles), which is higher than the LGMD VCEP threshold (<0.00009) for PM2_Supporting, and therefore does not meet this criterion. An in vitro assay in an heterologous cell system has demonstrated that this variant disrupts membrane localization of the sarcoglycan complex (PS3_Moderate, Washington University internal data communication). The computational predictor REVEL gives a score of 0.84, which is above the threshold of 0.7, evidence that correlates with impact to SGCA function (PP3). 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 2.0.0; 05/01/2026): PM3_Strong, PP4, PS3_Moderate, PP3.
