Submissions by phenotype
not specified Uncertain:1
The c.4G>A (p.A2T) alteration is located in exon 1 (coding exon 1) of the IAH1 gene. This alteration results from a G to A substitution at nucleotide position 4, causing the alanine (A) at amino acid position 2 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
