Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 10, 2023The c.1696A>G (p.R566G) alteration is located in exon 10 (coding exon 8) of the SPARCL1 gene. This alteration results from a A to G substitution at nucleotide position 1696, causing the arginine (R) at amino acid position 566 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
