Variant 10-68306795-C-A details in Genebe, Genetics Data Aggregator

Variant summary

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

The NM_022129.4(PBLD):c.50G>T(p.Arg17Leu) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000657 in 152,130 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 14/21 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. R17C) has been classified as Likely benign.

The c.50G>T (p.R17L) alteration is located in exon 2 (coding exon 1) of the PBLD gene. This alteration results from a G to T substitution at nucleotide position 50, causing the arginine (R) at amino acid position 17 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
