Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 02, 2022The c.1576C>T (p.R526W) alteration is located in exon 9 (coding exon 7) of the SPARCL1 gene. This alteration results from a C to T substitution at nucleotide position 1576, causing the arginine (R) at amino acid position 526 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
