Genes affected

BRSK2 (HGNC:11405): (BR serine/threonine kinase 2) Enables several functions, including ATP binding activity; ATPase binding activity; and protein kinase activity. Involved in several processes, including cellular protein metabolic process; intrinsic apoptotic signaling pathway in response to endoplasmic reticulum stress; and regulation of insulin secretion involved in cellular response to glucose stimulus. Located in centrosome and endoplasmic reticulum. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Verdict is Benign. Variant got -18 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.41).
• BP6: Variant 11-1436037-C-T is Benign according to our data. Variant chr11-1436037-C-T is described in ClinVar as [Likely_benign]. Clinvar id is 720380.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BS1: Variant frequency is greater than expected in population sas. gnomad4 allele frequency = 0.000976 (148/151610) while in subpopulation SAS AF= 0.00836 (40/4786). AF 95% confidence interval is 0.00631. There are 0 homozygotes in gnomad4. There are 73 alleles in male gnomad4 subpopulation. Median coverage is 28. This position pass quality control queck.
• BS2: High Homozygotes in GnomAdExome4 at 15 gene
