Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 27, 2022The c.4120C>T (p.R1374C) alteration is located in exon 25 (coding exon 24) of the RPAP1 gene. This alteration results from a C to T substitution at nucleotide position 4120, causing the arginine (R) at amino acid position 1374 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
