Genes affected

IGSF1 (HGNC:5948): (immunoglobulin superfamily member 1) This gene encodes a member of the immunoglobulin-like domain-containing superfamily. Proteins in this superfamily contain varying numbers of immunoglobulin-like domains and are thought to participate in the regulation of interactions between cells. Multiple transcript variants encoding different isoforms have been found for this gene.[provided by RefSeq, Jan 2010]

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -10 ACMG points.

BP4

Computational evidence support a benign effect (BayesDel_noAF=-0.6).

BP7

Synonymous conserved (PhyloP=0.025 with no splicing effect.

BS1

Variant frequency is greater than expected in population nfe. gnomad4_exome allele frequency = 0.0000264 (29/1097907) while in subpopulation NFE AF= 0.0000333 (28/841830). AF 95% confidence interval is 0.0000231. There are 0 homozygotes in gnomad4_exome. There are 9 alleles in male gnomad4_exome subpopulation. Median coverage is 30. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting
