Genes affected

SERPINA7 (HGNC:11583): (serpin family A member 7) There are three proteins including thyroxine-binding globulin (TBG), transthyretin and albumin responsible for carrying the thyroid hormones thyroxine (T4) and 3,5,3'-triiodothyronine (T3) in the bloodstream. This gene encodes the major thyroid hormone transport protein, TBG, in serum. It belongs to the serpin family in genomics, but the protein has no inhibitory function like many other members of the serpin family. Mutations in this gene result in TGB deficiency, which has been classified as partial deficiency, complete deficiency, and excess, based on the level of serum TBG. Alternatively spliced transcript variants encoding different isoforms have been found, but the full-length nature of these variants has not been determined.[provided by RefSeq, Jun 2012]

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -11 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.0030000508).

BP6

Variant X-106033506-T-G is Benign according to our data. Variant chrX-106033506-T-G is described in ClinVar as [Benign]. Clinvar id is 777816.Status of the report is criteria_provided_single_submitter, 1 stars.

BS1

Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.00477 (534/111864) while in subpopulation AFR AF= 0.0164 (506/30805). AF 95% confidence interval is 0.0152. There are 6 homozygotes in gnomad4. There are 154 alleles in male gnomad4 subpopulation. Median coverage is 23. This position pass quality control queck.

BS2

High Homozygotes in GnomAd4 at 6 XL geneVariant has number of homozygotes lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.
