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

Verdict is Benign. Variant got -10 ACMG points.

• BP6: Variant 8-115411485-GA-G is Benign according to our data. Variant chr8-115411485-GA-G is described in ClinVar as [Likely_benign]. Clinvar id is 361567.Status of the report is criteria_provided_single_submitter, 1 stars.
• BS1: Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.000894 (136/152118) while in subpopulation AFR AF= 0.00303 (126/41516). AF 95% confidence interval is 0.0026. There are 0 homozygotes in gnomad4. There are 65 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
• BS2: High AC in GnomAd4 at 136 AD gene.
