Ida Ertmanska changed review comment from: PMID: 41555919 Wang et al., 2026 2 unrelated female probands with retinitis pigmentosa and sensorineural deafness. They each had heterozygous de novo variants in DHX16: NM_003587 c.2474C>T, p.Ser825Phe and NM_003587.5 c.1360C>T, p.Arg454Trp respectively. Case 1 presented with hypotonia; delayed motor development was noted in Case 2. Overall, no overt myopathy noted in these cases. PMID: 40326698 Clay et al., 2025 3-year-old female, initially presented at 7 months of age, with mild developmental delay, ocular anomalies, dysmorphia, and increased infections. Trio WES detected a heterozygous de novo DHX16 variant, c.692G>C; p.R231P. Normal hearing, no hypotonia or myopathy. Authors argue the milder presentation may stem from this mutation being upstream of the functional helicase binding domain, where other variants were previously reported. PMID: 40141454 Kalampokini et al., 2025 Report of a 36-year-old female with neuromuscular disease, sensorineural hearing loss (diagnosed at 13 months), retinitis pigmentosa, and primary ovarian insufficiency harboring a heterozygous de novo missense variant in DHX16 NM_003587.5:c.2032G>A, p (Glu678Lys) . She had gait difficulties with onset at 12 years; she became wheelchair bound at age 22 years. Visual symptoms (nyctalopia, photosensitivity, color, and peripheral vision problems) were noted at age 27 yrs. Her intellectual level was normal to high. Electromyography revealed changes compatible with myopathy, while NCS showed severe axonal sensorimotor peripheral polyneuropathy. PMID: 37664979 Drackley et al., 2023 Report of a female proband. Profound bilateral sensorineural hearing loss noted at birth. Vision issues started early with nyctalopia, followed by severe cone- and rod-mediated disease (likely retinitis pigmentosa) diagnosis at 2 years of age. Hypotonia, motor delays, muscle weakness were present at 12–18 months of age. CMT testing uninformative. Skeletal muscle biopsy showed myopathic changes, CK elevated at 1000 U/L.

CK measurement = 1371 U/L. At the age of 3 years, the patient could move her hands and head but could not sit without support; progressive spasticity was noted.

PMID: 36211162 Archana et al., 2022 Male proband with bilateral severe hearing impairment noted at 4 months. He was not able to fixate on objects at 18 months. He had history of infantile spasms.

Zornitza Stark gene: DHX16 was added gene: DHX16 was added to Congenital myopathy. Sources: Literature Mode of inheritance for gene: DHX16 was set to MONOALLELIC, autosomal or pseudoautosomal, NOT imprinted Publications for gene: DHX16 were set to 31256877 Phenotypes for gene: DHX16 were set to Neuromuscular disease and ocular or auditory anomalies with or without seizures, MIM# 618733 Review for gene: DHX16 was set to AMBER gene: DHX16 was marked as current diagnostic Added comment: This gene is somewhat difficult to place on the right panels. Overall, there are four unrelated individuals reported with de novo missense variants. Three of the individuals died in infancy, so phenotypic information is limited, though hypotonia was prominent. Two had seizures. Individual with long-term survival had a progressive course, evidence of neuropathy, myopathy, loss of hearing and vision, and normal IQ. Sources: Literature |
