Genes affected

AMMECR1 (HGNC:467): (AMMECR nuclear protein 1) The exact function of this gene is not known, however, submicroscopic deletion of the X chromosome including this gene, COL4A5, and FACL4 genes, result in a contiguous gene deletion syndrome, the AMME complex (Alport syndrome, mental retardation, midface hypoplasia, and elliptocytosis). Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jan 2010]

AMMECR1 Gene-Disease associations (from GenCC):

• midface hypoplasia, hearing impairment, elliptocytosis, and nephrocalcinosis

  Inheritance: XL Classification: STRONG, MODERATE Submitted by: Labcorp Genetics (formerly Invitae), Illumina
• Alport syndrome-intellectual disability-midface hypoplasia-elliptocytosis syndrome

  Inheritance: XL Classification: SUPPORTIVE Submitted by: Orphanet

ACMG classification

Our verdict: Uncertain_significance. The variant received 2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
