Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 03, 2022The c.1929C>G (p.I643M) alteration is located in exon 8 (coding exon 8) of the FAM171A1 gene. This alteration results from a C to G substitution at nucleotide position 1929, causing the isoleucine (I) at amino acid position 643 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
