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]

The c.931G>A (p.A311T) alteration is located in exon 6 (coding exon 6) of the AMMECR1 gene. This alteration results from a G to A substitution at nucleotide position 931, causing the alanine (A) at amino acid position 311 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
