Genes affected

STON2 (HGNC:30652): (stonin 2) This gene encodes a protein which is a membrane protein involved in regulating endocytotic complexes. The protein product is described as one of the clathrin-associated sorting proteins, adaptor molecules which ensure specific proteins are internalized. The encoded protein has also been shown to participate in synaptic vesicle recycling through interaction with synaptotagmin 1 required for neurotransmission. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jan 2012]

STON2 (HGNC:):

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.94).
• BS1: Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.0165 (2509/152202) while in subpopulation AFR AF= 0.0505 (2097/41512). AF 95% confidence interval is 0.0487. There are 69 homozygotes in gnomad4. There are 1174 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd4 at 69 gene
