Treacher Collins syndrome 1 Uncertain:1
Based on the classification scheme VCGS_Germline_v1.3.4, this variant is classified as VUS-3A Following criteria are met: 0102 - Loss of function is a known mechanism of disease in this gene and is associated with Treacher Collins syndrome 1 (MIM#154500). (I) 0107 - This gene is associated with autosomal dominant disease. (I) 0112 - The condition associated with this gene has incomplete penetrance. While penetrance for Treacher Collins syndrome 1 (MIM#154500) is high, reduced penetrance has been reported for TCOF1 (GeneReviews). (I) 0115 - Variants in this gene are known to have variable expressivity. Significant inter and intra familial variability has been reported (GeneReviews). (I) 0200 - Variant is predicted to result in a missense amino acid change from glutamic acid to glutamine. (I) 0251 - This variant is heterozygous. (I) 0301 - Variant is absent from gnomAD (both v2 and v3). (SP) 0309 - An alternative amino acid change at the same position has been observed in gnomAD (v2: 1 heterozygote, 0 homozygotes). (I) 0503 - Missense variant consistently predicted to be tolerated by multiple in silico tools or not conserved in placental mammals with a minor amino acid change. (I) 0603 - Missense variant in a region that is highly intolerant to missense variation (high constraint region in DECIPHER). (SP) 0705 - No comparable missense variants have previous evidence for pathogenicity. (I) 0807 - This variant has no previous evidence of pathogenicity. (I) 0905 - No published segregation evidence has been identified for this variant. (I) 1007 - No published functional evidence has been identified for this variant. (I) 1203 - This variant has been shown to be de novo in the proband (parental status confirmed) (by trio analysis). (SP) Legend: (SP) - Supporting pathogenic, (I) - Information, (SB) - Supporting benign -
