chr12-105144438-G-A

Variant summary

Our verdict is Benign. The variant received -13 ACMG points: 0P and 13B. BP4_StrongBP6BS1BS2

The NM_015275.3(WASHC4):​c.2162G>A​(p.Arg721His) variant causes a missense change. The variant allele was found at a frequency of 0.000504 in 1,610,564 control chromosomes in the GnomAD database, including 5 homozygotes. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R721S) has been classified as Uncertain significance.

Genes affected
WASHC4 (HGNC:29174): (WASH complex subunit 4) This gene encodes a component of the WASH complex, which functions in the intracellular transport of endosomes. Mutations in this gene have been detected in individuals with autosomal recessive cognitive disability. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jun 2014]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -13 ACMG points.

BP4
Computational evidence support a benign effect (MetaRNN=0.009955913).
BP6
Variant 12-105144438-G-A is Benign according to our data. Variant chr12-105144438-G-A is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 435577.
BS1
Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.00242 (361/149286) while in subpopulation AFR AF = 0.00827 (337/40768). AF 95% confidence interval is 0.00754. There are 3 homozygotes in GnomAd4. There are 178 alleles in the male GnomAd4 subpopulation. Median coverage is 31. This position passed quality control check.
BS2
High Homozygotes in GnomAd4 at 3 AR,Unknown gene
