Genetic Variant PLVAP:p.Pro432Ala (chr19-17360556-G-C) – ACMG Classification: Benign (-8 pts)

Variant summary

Our verdict is Benign. The variant received -8 ACMG points: 0P and 8B. BP4_StrongBS1

The NM_031310.3(PLVAP):c.1294C>G(p.Pro432Ala) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000279 in 1,613,904 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 16/21 in silico tools predict a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. P432S) has been classified as Uncertain significance.

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -8 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.059972346).

BS1

Variant frequency is greater than expected in population eas. GnomAdExome4 allele frequency = 0.0000301 (44/1461720) while in subpopulation EAS AF = 0.00106 (42/39700). AF 95% confidence interval is 0.000804. There are 0 homozygotes in GnomAdExome4. There are 19 alleles in the male GnomAdExome4 subpopulation. Median coverage is 32. This position passed quality control check.
