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: Uncertain_significance. The variant received 3 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PM4: Nonframeshift variant in NON repetitive region in NM_173849.3. Strenght limited to Supporting due to length of the change: 1aa.
