Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 02, 2024The c.944A>T (p.K315M) alteration is located in exon 8 (coding exon 6) of the FAM114A1 gene. This alteration results from a A to T substitution at nucleotide position 944, causing the lysine (K) at amino acid position 315 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
