Variant summary

Our verdict is Uncertain significance. Variant got 0 ACMG points: 2P and 2B. PM2 BP4_Moderate

The NM_198285.3(WDR86):​c.1055C>T​(p.Pro352Leu) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000016 in 1,249,048 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 12/17 in silico tools predict 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. P352R) has been classified as Uncertain significance.

The c.1055C>T (p.P352L) alteration is located in exon 6 (coding exon 6) of the WDR86 gene. This alteration results from a C to T substitution at nucleotide position 1055, causing the proline (P) at amino acid position 352 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
