The SPARCL1 c.971C>T variant is predicted to result in the amino acid substitution p.Pro324Leu. To our knowledge, this variant has not been reported in the literature in individuals with SPARCL1-related disorders. This variant is reported in 0.0029% of alleles in individuals of Latino descent in gnomAD (http://gnomad.broadinstitute.org/variant/4-88414981-G-A). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
