Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 15, 2024The c.1488C>A (p.D496E) alteration is located in exon 5 (coding exon 5) of the IRX4 gene. This alteration results from a C to A substitution at nucleotide position 1488, causing the aspartic acid (D) at amino acid position 496 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
