Description

The MPZL2 c.72delA variant is predicted to result in a frameshift and premature protein termination (p.Ile24Metfs*22). This variant has been reported in patients with autosomal recessive hearing loss (Bademci. 2018. PubMed ID: 29982980; Wesdorp. 2018. PubMed ID: 29961571; Safka Brozkova. 2021. PubMed ID: 34062854). This variant is reported in 0.38% of alleles in individuals of Ashkenazi Jewish descent in gnomAD (http://gnomad.broadinstitute.org/variant/11-118133798-CT-C). Frameshift variants in MPZL2 are expected to be pathogenic. This variant is interpreted as pathogenic.
