Genes affected

GRHL2 (HGNC:2799): (grainyhead like transcription factor 2) The protein encoded by this gene is a transcription factor that can act as a homodimer or as a heterodimer with either GRHL1 or GRHL3. Defects in this gene are a cause of non-syndromic sensorineural deafness autosomal dominant type 28 (DFNA28).[provided by RefSeq, Mar 2009]

Variant classified as Uncertain Significance - Favor Benign. The p.Leu107Met var iant in GRHL2 has now been reported by our laboratory in one individual with hea ring loss and a reportedly unaffected parent (this individual). It has not been reported in large population studies. The leucine (Leu) at position 107 is not conserved in mammals or evolutionary distant species, with one mammal (Bushbaby) having a methionine (Met) at this position, supporting that a change at this po sition may be tolerated. Additional computational prediction tools do not provid e strong support for or against an impact to the protein. In summary, while the clinical significance of the p.Leu107Met variant is uncertain, available data s uggest that it is more likely to be benign. -
