Variant summary

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

The NM_001029874.3(REP15):c.505C>T(p.Pro169Ser) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000254 in 1,613,830 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. P169L) has been classified as Uncertain significance.

Collection Method: clinical testing

The c.505C>T (p.P169S) alteration is located in exon 1 (coding exon 1) of the REP15 gene. This alteration results from a C to T substitution at nucleotide position 505, causing the proline (P) at amino acid position 169 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
