Genes affected

TGDS (HGNC:20324): (TDP-glucose 4,6-dehydratase) The protein encoded by this gene is a member of the short-chain dehydrogenases/reductases (SDR) superfamily, and is thought to contain a nicotinamide adenine dinucleotide (NAD) binding domain. This large SDR family of enzymes is involved in the metabolism of a variety of compounds, including prostaglandins, retinoids, lipids, steroid hormones, and xenobiotics. Mutations in this gene have been associated with Catel-Manzke syndrome, which is characterized by Pierre Robin sequence, and radial deviation of the index finger due to the presence of an accessory bone between the index finger and its proximal phalanx. Pierre Robin sequence is defined by an undersized jaw, backwards displacement of the tongue base that causes an obstruction of the airways, and can also be associated with a cleft palate. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jan 2015]

ACMG classification

Our verdict: Likely_pathogenic. The variant received 7 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_014305.4
• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 7 curated pathogenic missense variants (we use a threshold of 10). The gene has 2 curated benign missense variants. Gene score misZ: 0.29997 (below the threshold of 3.09). Trascript score misZ: 0.81559 (below the threshold of 3.09). GenCC associations: The gene is linked to Catel-Manzke syndrome.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.803
• PP5: Variant 13-94590872-A-C is Pathogenic according to our data. Variant chr13-94590872-A-C is described in ClinVar as Pathogenic. ClinVar VariationId is 162458.Status of the report is no_assertion_criteria_provided, 0 stars.
