Genes affected

INF2 (HGNC:23791): (inverted formin 2) This gene represents a member of the formin family of proteins. It is considered a diaphanous formin due to the presence of a diaphanous inhibitory domain located at the N-terminus of the encoded protein. Studies of a similar mouse protein indicate that the protein encoded by this locus may function in polymerization and depolymerization of actin filaments. Mutations at this locus have been associated with focal segmental glomerulosclerosis 5.[provided by RefSeq, Aug 2010]

Variant summary: INF2 c.1957G>A (p.Glu653Lys) results in a conservative amino acid change in the encoded protein sequence. Three of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 7.3e-05 in 247682 control chromosomes. The observed variant frequency is approximately 116 fold of the estimated maximal expected allele frequency for a pathogenic variant in INF2 causing Charcot-Marie-Tooth disease dominant intermediate E phenotype (6.3e-07). To our knowledge, no occurrence of c.1957G>A in individuals affected with Charcot-Marie-Tooth disease dominant intermediate E and no experimental evidence demonstrating its impact on protein function have been reported. ClinVar contains an entry for this variant (Variation ID: 540042). Based on the evidence outlined above, the variant was classified as likely benign. -

Significance: Likely benign

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
