Genes affected

GSC (HGNC:4612): (goosecoid homeobox) This gene encodes a member of the bicoid subfamily of the paired (PRD) homeobox family of proteins. The encoded protein acts as a transcription factor and may be autoregulatory. A similar protein in mice plays a role in craniofacial and rib cage development during embryogenesis.

ACMG classification

Verdict is Likely_pathogenic. Variant got 7 ACMG points.

• PVS1: Splicing +-2 bp (donor or acceptor) variant, product NOT destroyed by NMD, known LOF gene, truncates exone, which is 0.5839793 fraction of the gene.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 14-94769660-C-G is Pathogenic according to our data. Variant chr14-94769660-C-G is described in ClinVar as [Pathogenic]. Clinvar id is 126524.Status of the report is no_assertion_criteria_provided, 0 stars.
