Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 06, 2021The c.1604G>A (p.R535Q) alteration is located in exon 10 (coding exon 10) of the DCST2 gene. This alteration results from a G to A substitution at nucleotide position 1604, causing the arginine (R) at amino acid position 535 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
