Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 09, 2021The c.7A>G (p.K3E) alteration is located in exon 1 (coding exon 1) of the PRPSAP1 gene. This alteration results from a A to G substitution at nucleotide position 7, causing the lysine (K) at amino acid position 3 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
