Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 13, 2021The c.3430G>A (p.G1144R) alteration is located in exon 20 (coding exon 20) of the IGDCC4 gene. This alteration results from a G to A substitution at nucleotide position 3430, causing the glycine (G) at amino acid position 1144 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
