Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 14, 2023The c.221G>A (p.R74K) alteration is located in exon 2 (coding exon 2) of the PSORS1C2 gene. This alteration results from a G to A substitution at nucleotide position 221, causing the arginine (R) at amino acid position 74 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
