Variant summary

Our verdict is Benign. The variant received -20 ACMG points: 0P and 20B. BP4_StrongBP6_Very_StrongBS1BS2

The NM_001017420.3(ESCO2):​c.764T>C​(p.Phe255Ser) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00199 in 1,605,628 control chromosomes in the GnomAD database, including 79 homozygotes. In-silico tool predicts a benign outcome for this variant. 16/21 in silico tools predict 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. F255L) has been classified as Uncertain significance.

Genes affected
ESCO2 (HGNC:27230): (establishment of sister chromatid cohesion N-acetyltransferase 2) This gene encodes a protein that may have acetyltransferase activity and may be required for the establishment of sister chromatid cohesion during the S phase of mitosis. Mutations in this gene have been associated with Roberts syndrome. [provided by RefSeq, Jul 2008]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -20 ACMG points.

BP4
Computational evidence support a benign effect (MetaRNN=0.0027889013).
BP6
Variant 8-27777072-T-C is Benign according to our data. Variant chr8-27777072-T-C is described in ClinVar as Benign/Likely_benign. ClinVar VariationId is 196300.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
BS1
Variant frequency is greater than expected in population amr. GnomAd4 allele frequency = 0.00262 (399/152270) while in subpopulation AMR AF = 0.0182 (279/15300). AF 95% confidence interval is 0.0165. There are 8 homozygotes in GnomAd4. There are 197 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check.
BS2
High Homozygotes in GnomAd4 at 8 AR gene

Review Status:criteria provided, single submitter
Collection Method:clinical testing

This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). No publications were found based on this search. Allele frequency data from public databases allowed determination this variant is unlikely to cause disease. Therefore, this variant is classified as likely benign.
