Submissions by phenotype
not specified Uncertain:1
The c.1361G>A (p.R454H) alteration is located in exon 6 (coding exon 6) of the SNTB1 gene. This alteration results from a G to A substitution at nucleotide position 1361, causing the arginine (R) at amino acid position 454 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
