Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 07, 2023The c.1198G>C (p.E400Q) alteration is located in exon 5 (coding exon 3) of the SPARCL1 gene. This alteration results from a G to C substitution at nucleotide position 1198, causing the glutamic acid (E) at amino acid position 400 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
