Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 04, 2023The c.743G>T (p.R248I) alteration is located in exon 4 (coding exon 4) of the ZNF440 gene. This alteration results from a G to T substitution at nucleotide position 743, causing the arginine (R) at amino acid position 248 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
