Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 06, 2022The c.701C>T (p.T234M) alteration is located in exon 7 (coding exon 7) of the PRPSAP1 gene. This alteration results from a C to T substitution at nucleotide position 701, causing the threonine (T) at amino acid position 234 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
