Genes affected
DIAPH1 (HGNC:2876): (diaphanous related formin 1) This gene is a homolog of the Drosophila diaphanous gene, and has been linked to autosomal dominant, fully penetrant, nonsyndromic sensorineural progressive low-frequency hearing loss. Actin polymerization involves proteins known to interact with diaphanous protein in Drosophila and mouse. It has therefore been speculated that this gene may have a role in the regulation of actin polymerization in hair cells of the inner ear. Alternatively spliced transcript variants encoding distinct isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -12 ACMG points.

BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.37).
BP6
Variant 5-141528547-C-T is Benign according to our data. Variant chr5-141528547-C-T is described in ClinVar as [Likely_benign]. Clinvar id is 163068.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr5-141528547-C-T is described in Lovd as [Likely_benign].
BP7
Synonymous conserved (PhyloP=-2.82 with no splicing effect.
BS2
High AC in GnomAd4 at 8 AD gene. Variant has AC lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.
