Variant summary

Our verdict is Benign. The variant received -16 ACMG points: 0P and 16B. BP4_StrongBP6_Very_StrongBS1

The NM_031475.3(ESPN):c.1048C>T(p.Pro350Ser) variant causes a missense change. The variant allele was found at a frequency of 0.000136 in 1,614,226 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Likely benign (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. P350R) has been classified as Likely benign.

Genes affected

ESPN (HGNC:13281): (espin) This gene encodes a multifunctional actin-bundling protein. It plays a major role in regulating the organization, dimensions, dynamics, and signaling capacities of the actin filament-rich, microvillus-type specializations that mediate sensory transduction in various mechanosensory and chemosensory cells. Mutations in this gene are associated with autosomal recessive neurosensory deafness, and autosomal dominant sensorineural deafness without vestibular involvement. [provided by RefSeq, Nov 2009]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -16 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.009685338).

BP6

Variant 1-6444538-C-T is Benign according to our data. Variant chr1-6444538-C-T is described in ClinVar as Likely_benign. ClinVar VariationId is 163412.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

BS1

Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.000748 (114/152340) while in subpopulation AFR AF = 0.00267 (111/41578). AF 95% confidence interval is 0.00227. There are 0 homozygotes in GnomAd4. There are 52 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check.
