Genes affected
DIAPH2 (HGNC:2877): (diaphanous related formin 2) The product of this gene belongs to the diaphanous subfamily of the formin homology family of proteins. This gene may play a role in the development and normal function of the ovaries. Defects in this gene have been linked to premature ovarian failure 2. Alternatively spliced transcript variants encoding different isoforms have been identified. [provided by RefSeq, Jul 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 20, 2022The c.16G>A (p.A6T) alteration is located in exon 1 (coding exon 1) of the DIAPH2 gene. This alteration results from a G to A substitution at nucleotide position 16, causing the alanine (A) at amino acid position 6 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
