Genes affected

PPARG (HGNC:9236): (peroxisome proliferator activated receptor gamma) This gene encodes a member of the peroxisome proliferator-activated receptor (PPAR) subfamily of nuclear receptors. PPARs form heterodimers with retinoid X receptors (RXRs) and these heterodimers regulate transcription of various genes. Three subtypes of PPARs are known: PPAR-alpha, PPAR-delta, and PPAR-gamma. The protein encoded by this gene is PPAR-gamma and is a regulator of adipocyte differentiation. Additionally, PPAR-gamma has been implicated in the pathology of numerous diseases including obesity, diabetes, atherosclerosis and cancer. Alternatively spliced transcript variants that encode different isoforms have been described. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Likely_pathogenic. Variant got 7 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant in the PPARG gene, where missense mutations are typically associated with disease (based on misZ statistic). The gene has 16 curated pathogenic missense variants (we use a threshold of 10). The gene has 5 curated benign missense variants. Gene score misZ: 2.1192 (below the threshold of 3.09). Trascript score misZ: 3.0978 (above the threshold of 3.09). GenCC associations: The gene is linked to PPARG-related familial partial lipodystrophy, Berardinelli-Seip congenital lipodystrophy.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.892
• PP5: Variant 3-12405897-G-A is Pathogenic according to our data. Variant chr3-12405897-G-A is described in ClinVar as [Likely_pathogenic]. Clinvar id is 436398.Status of the report is criteria_provided_single_submitter, 1 stars.
