Genes affected
EIF4H (HGNC:12741): (eukaryotic translation initiation factor 4H) This gene encodes one of the translation initiation factors, which functions to stimulate the initiation of protein synthesis at the level of mRNA utilization. This gene is deleted in Williams syndrome, a multisystem developmental disorder caused by the deletion of contiguous genes at 7q11.23. Alternative splicing of this gene generates 2 transcript variants. [provided by RefSeq, Jul 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 17, 2023The c.659C>T (p.T220M) alteration is located in exon 7 (coding exon 7) of the EIF4H gene. This alteration results from a C to T substitution at nucleotide position 659, causing the threonine (T) at amino acid position 220 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
