Genes affected

TRPS1 (HGNC:12340): (transcriptional repressor GATA binding 1) This gene encodes a transcription factor that represses GATA-regulated genes and binds to a dynein light chain protein. Binding of the encoded protein to the dynein light chain protein affects binding to GATA consensus sequences and suppresses its transcriptional activity. Defects in this gene are a cause of tricho-rhino-phalangeal syndrome (TRPS) types I-III. [provided by RefSeq, Jul 2008]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -12 ACMG points.

BP4

Computational evidence support a benign effect (BayesDel_noAF=-0.74).

BS1

Variant frequency is greater than expected in population nfe. GnomAd4 allele frequency = 0.000223 (34/152206) while in subpopulation NFE AF = 0.000191 (13/68004). AF 95% confidence interval is 0.000112. There are 0 homozygotes in GnomAd4. There are 24 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check.

BS2

High AC in GnomAd4 at 34 AD gene.
