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.

GSC Gene-Disease associations (from GenCC):

• short stature-auditory canal atresia-mandibular hypoplasia-skeletal anomalies syndrome

  Inheritance: AR Classification: STRONG, MODERATE, SUPPORTIVE Submitted by: G2P, Labcorp Genetics (formerly Invitae), Orphanet

ACMG classification

Our verdict: Likely_pathogenic. The variant received 7 ACMG points.

• PVS1: Splicing +-2 bp (donor or acceptor) variant, product NOT destroyed by NMD, known LOF gene, truncates exone, which is 0.5852713 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 VariationId is 126524.Status of the report is no_assertion_criteria_provided, 0 stars.
