Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 08, 2022The c.476G>A (p.R159Q) alteration is located in exon 4 (coding exon 4) of the ARPIN gene. This alteration results from a G to A substitution at nucleotide position 476, causing the arginine (R) at amino acid position 159 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
