Genes affected

TRIM44 (HGNC:19016): (tripartite motif containing 44) This gene encodes a member of the tripartite motif (TRIM) family. The TRIM motif includes three zinc-binding domains, namely a RING, a B-box type 1 and a B-box type 2, and a coiled-coil region. [provided by RefSeq, Jul 2008]

TRIM44 Gene-Disease associations (from GenCC):

• isolated aniridia

  Inheritance: AD Classification: SUPPORTIVE Submitted by: Orphanet
• aniridia 3

  Inheritance: AD Classification: LIMITED Submitted by: G2P, Labcorp Genetics (formerly Invitae), Genomics England PanelApp, Ambry Genetics

ACMG classification

Our verdict: Benign. The variant received -8 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.056700796).
• BS2: High AC in GnomAd4 at 7 AD gene.

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.209C>T (p.P70L) alteration is located in exon 1 (coding exon 1) of the TRIM44 gene. This alteration results from a C to T substitution at nucleotide position 209, causing the proline (P) at amino acid position 70 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
