Variant chr7-132133051-C-G details in Genebe, Genetics Data Aggregator

Variant summary

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

The NM_020911.2(PLXNA4):c.5587G>C(p.Glu1863Gln) variant causes a missense, splice region change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.00000137 in 1,461,364 control chromosomes in the GnomAD database, with no homozygous occurrence. 3/3 splice prediction tools predict no significant impact on normal splicing. Variant has been reported in ClinVar as Uncertain significance (no stars).

The PLXNA4 c.5587G>C variant is predicted to result in the amino acid substitution p.Glu1863Gln. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.0065% of alleles in individuals of African descent in gnomAD. This variant is located near a canonical splice junction, but is not expected to alter splicing according to available splicing prediction algorithms (Alamut Visual Plus v1.6.1). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
