Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 30, 2022The c.389G>A (p.R130Q) alteration is located in exon 3 (coding exon 3) of the SNAPC1 gene. This alteration results from a G to A substitution at nucleotide position 389, causing the arginine (R) at amino acid position 130 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
