Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 29, 2023The c.797G>A (p.R266H) alteration is located in exon 3 (coding exon 2) of the SLC45A3 gene. This alteration results from a G to A substitution at nucleotide position 797, causing the arginine (R) at amino acid position 266 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
