Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 25, 2024The c.1022G>A (p.R341Q) alteration is located in exon 6 (coding exon 6) of the FAM131A gene. This alteration results from a G to A substitution at nucleotide position 1022, causing the arginine (R) at amino acid position 341 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
