Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 15, 2024The c.710G>T (p.R237M) alteration is located in exon 6 (coding exon 6) of the SAMSN1 gene. This alteration results from a G to T substitution at nucleotide position 710, causing the arginine (R) at amino acid position 237 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
