Genes affected
PIK3R1 (HGNC:8979): (phosphoinositide-3-kinase regulatory subunit 1) Phosphatidylinositol 3-kinase phosphorylates the inositol ring of phosphatidylinositol at the 3-prime position. The enzyme comprises a 110 kD catalytic subunit and a regulatory subunit of either 85, 55, or 50 kD. This gene encodes the 85 kD regulatory subunit. Phosphatidylinositol 3-kinase plays an important role in the metabolic actions of insulin, and a mutation in this gene has been associated with insulin resistance. Alternative splicing of this gene results in four transcript variants encoding different isoforms. [provided by RefSeq, Jun 2011]

ACMG classification
Classification made for transcript
Verdict is Likely_pathogenic. Variant got 6 ACMG points.
PM1
?
In a hotspot region, there are 3 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 0 benign, 4 uncertain in NM_181523.3
PM2
?
Very rare variant in population databases, with high coverage;
PM4
?
Nonframeshift variant in NON repetitive region in NM_181523.3. Strenght limited to Supporting due to length of the change: 1aa.
PP5
?
Variant 5-68295303-AGAC-A is Pathogenic according to our data. Variant chr5-68295303-AGAC-A is described in ClinVar as [Likely_pathogenic]. Clinvar id is 376262.Status of the report is no_assertion_criteria_provided, 0 stars.
