Submissions by phenotype
not specified Uncertain:1
The c.852T>G (p.H284Q) alteration is located in exon 6 (coding exon 6) of the DNASE2B gene. This alteration results from a T to G substitution at nucleotide position 852, causing the histidine (H) at amino acid position 284 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
