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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 05, 2024The c.928C>T (p.L310F) alteration is located in exon 6 (coding exon 6) of the AMMECR1 gene. This alteration results from a C to T substitution at nucleotide position 928, causing the leucine (L) at amino acid position 310 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
