Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 30, 2024The c.146G>A (p.R49Q) alteration is located in exon 2 (coding exon 2) of the SMKR1 gene. This alteration results from a G to A substitution at nucleotide position 146, causing the arginine (R) at amino acid position 49 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
