The p.Gly71Arg variant has not been reported in the literature nor previously identified by our laboratory. The variant occurs in the last base of exon 1. This position has been shown to be part of the splicing consensus sequence and variants involving this position sometimes affect splicing. In-silico or computational prediction software (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer, HumanSpliceFinder) predicts a greater than 10% difference in splicing in 4 out of 5 different programs. This residue is conserved in mammals but not in lower organisms, and computational analyses (SIFT, AlignGVGD) do not suggest a high likelihood of impact to the protein. However, the information from these software analyses is not predictive enough to rule out pathogenicity. In summary, based on the above information, the clinical significance of this variant cannot be determined with certainty at this time, although we would lean towards a more pathogenic role for this variant. This variant is classified as Predicted Pathogenic.
