Variant summary

Our verdict is Uncertain significance. Variant got 0 ACMG points: 2P and 2B. PM2BP4_Moderate

The NM_015540.4(RPAP1):ā€‹c.3335G>Cā€‹(p.Arg1112Pro) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000124 in 1,613,700 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 12/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (ā˜…). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R1112Q) has been classified as Likely benign.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 27, 2022The c.3335G>C (p.R1112P) alteration is located in exon 22 (coding exon 21) of the RPAP1 gene. This alteration results from a G to C substitution at nucleotide position 3335, causing the arginine (R) at amino acid position 1112 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
