Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 27, 2024The c.532C>T (p.R178W) alteration is located in exon 4 (coding exon 4) of the ZCCHC4 gene. This alteration results from a C to T substitution at nucleotide position 532, causing the arginine (R) at amino acid position 178 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
